Progress bars are used in an interface to pass on information to users related to the known progression of a certain operation. They visually signify how far the operation has advanced and can be circular or horizontal. They can also be indefinite to indicate the loading or processing of data. In this article, we’re going to learn how to create a horizontal progress bar with the Vuetify progress linear component.

The v-progress-linear Component

Vuetify provides the v-progress-linear component for creating a horizontal progress bar.

<template>
  <v-app>
    <v-progress-linear></v-progress-linear>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Progress Bar Value

The progress linear component comes with the value prop that we can use to set the progress bar to a determinate value between 0 and 100 inclusive:

<template>
  <v-app>
    <v-row justify="center" class="ma-4">
      <v-col sm="6">
        <v-progress-linear value="40"></v-progress-linear>
      </v-col>
    </v-row>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Progress Linear v-model

We can set up a two-way binding between the value of the progress bar and a variable using v-model:

<template>
  <v-app>
    <v-row justify="center" class="ma-4">
      <v-col sm="6">
        <v-progress-linear v-model="value"></v-progress-linear>
      </v-col>
    </v-row>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    value: 30,
  }),
};
</script>

To see this two-way binding in action, let’s create two buttons to change the progress bar value and some text to display this value. We spaced the buttons apart with one of the Vuetify spacing helper classes (ma-2).

<template>
  <v-app>
    <v-row justify="center" class="ma-4">
      <v-col sm="6">
        <v-row>
          <v-progress-linear v-model="value"></v-progress-linear>
        </v-row>
        <v-row justify="center">{{ value }}%</v-row>
        <v-row justify="center">
          <v-btn class="ma-2" @click="value -= 10" color="red" dark>
            -10
          </v-btn>
          <v-btn class="ma-2" @click="value += 10" color="green" dark>
            +10
          </v-btn>
        </v-row>
      </v-col>
    </v-row>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    value: 30,
  }),
};
</script>

Progress Linear Buffer Value

A buffer state simultaneously represents two values. The primary value is controlled by v-model, while the buffer value is controlled by the buffer-value prop:

<template>
  <v-app>
    <v-row justify="center" class="ma-4">
      <v-col sm="8">
        <v-progress-linear
          v-model="value"
          :buffer-value="bufferValue"
        ></v-progress-linear>
        <br />
        <v-progress-linear
          v-model="value"
          :buffer-value="bufferValue"
          color="green"
        ></v-progress-linear>
        <br />
        <v-progress-linear
          v-model="value"
          :buffer-value="bufferValue"
          color="orange"
        ></v-progress-linear>
        <br />
        <v-progress-linear
          v-model="value"
          :buffer-value="bufferValue"
          color="purple accent-4"
        ></v-progress-linear>
      </v-col>
    </v-row>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data() {
    return {
      value: 10,
      bufferValue: 20,
      interval: 0,
    };
  },

  watch: {
    value(val) {
      if (val < 100) return;

      this.value = 0;
      this.bufferValue = 10;
      this.startBuffer();
    },
  },

  mounted() {
    this.startBuffer();
  },

  beforeDestroy() {
    clearInterval(this.interval);
  },

  methods: {
    startBuffer() {
      clearInterval(this.interval);

      this.interval = setInterval(() => {
        this.value += Math.random() * (15 - 5) + 5;
        this.bufferValue += Math.random() * (15 - 5) + 6;
      }, 1000);
    },
  },
};
</script>

Progress Bar Custom Colors

The Vuetify progress linear component comes with a color prop that allows us to customize the color of the horizontal progress bar:

<template>
  <v-app>
    <v-row justify="center" class="ma-4">
      <v-col sm="8">
        <v-progress-linear
          background-color="blue"
          color="red accent-2"
          value="20"
        ></v-progress-linear>
        <br />
        <v-progress-linear
          background-color="grey"
          color="yellow"
          value="40"
        ></v-progress-linear>
        <br />
        <v-progress-linear
          background-color="green lighten-3"
          color="green"
          value="60"
        ></v-progress-linear>
      </v-col>
    </v-row>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Progress Linear Indeterminate

We can display an indeterminate progress bar with the indeterminate prop.

<template>
  <v-app>
    <v-row justify="center" class="ma-4">
      <v-col sm="8">
        <v-progress-linear indeterminate color="red"></v-progress-linear>
        <br />
        <v-progress-linear indeterminate color="primary"></v-progress-linear>
        <br />
        <v-progress-linear indeterminate color="green"></v-progress-linear>
      </v-col>
    </v-row>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

The progress bar will animate continuously when indeterminate:

Reversed Progress Bar

Setting the reverse prop to true will display a reversed progress bar (right to left in LTR mode and left to right in RTL).

<template>
  <v-app>
    <v-row justify="center" class="ma-4">
      <v-col sm="8">
        <v-progress-linear
          color="indigo"
          value="15"
          reverse
        ></v-progress-linear>

        <br />

        <v-progress-linear
          color="teal"
          indeterminate
          reverse
        ></v-progress-linear>

        <br />

        <v-progress-linear
          buffer-value="55"
          color="red accent-2"
          reverse
          stream
          value="30"
        ></v-progress-linear>

        <br />

        <v-subheader
          >In specific cases you may want progress to display in left-to-right
          mode regardless of the application direction (LTR or
          RTL):</v-subheader
        >

        <v-progress-linear
          :reverse="$vuetify.rtl"
          value="15"
          color="yellow darken-3"
        ></v-progress-linear>
      </v-col>
    </v-row>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Progress Linear Rounded

We can add a border radius to the Vuetify progress linear component by setting the rounded prop to true:

<template>
  <v-app>
    <v-row justify="center" class="ma-4">
      <v-col sm="8">
        <v-progress-linear
          color="blue accent-2"
          rounded
          value="100"
        ></v-progress-linear>

        <br />

        <v-progress-linear color="pink" rounded value="100"></v-progress-linear>

        <br />

        <v-progress-linear
          color="orange"
          rounded
          value="100"
        ></v-progress-linear>

        <br />

        <v-progress-linear
          color="purple accent-4"
          rounded
          value="100"
        ></v-progress-linear>
      </v-col>
    </v-row>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Progress Bar Stream

The stream prop works with buffer-value to inform the user that some action is taking place.

<template>
  <v-app>
    <v-row justify="center" class="ma-4">
      <v-col sm="8">
        <v-progress-linear
          color="yellow darken-3"
          buffer-value="0"
          stream
        ></v-progress-linear>
        <br />
        <v-progress-linear
          color="primary"
          buffer-value="0"
          value="20"
          stream
        ></v-progress-linear>
        <br />
        <v-progress-linear
          buffer-value="50"
          stream
          color="red"
        ></v-progress-linear>
        <br />
        <v-progress-linear
          buffer-value="60"
          value="40"
          stream
          color="green"
        ></v-progress-linear>
      </v-col>
    </v-row>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Striped Progress Bar

The striped prop applies a striped background over the value portion of the horizontal progress bar.

<template>
  <v-app>
    <v-row justify="center" class="ma-4">
      <v-col sm="8">
        <v-progress-linear
          color="indigo"
          height="10"
          value="10"
          striped
        ></v-progress-linear>
        <br />
        <v-progress-linear
          color="cyan"
          height="10"
          value="20"
          striped
        ></v-progress-linear>
        <br />
        <v-progress-linear
          height="10"
          value="45"
          striped
          color="green"
        ></v-progress-linear>
        <br />
        <v-progress-linear
          value="60"
          height="10"
          striped
          color="orange"
        ></v-progress-linear>
      </v-col>
    </v-row>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Default Slot

With the default slot of the progress linear component, we can display custom components inside the progress bar.

<template>
  <v-app>
    <v-row justify="center" class="ma-4">
      <v-col sm="8">
        <v-progress-linear
          :indeterminate="query"
          :query="true"
          height="25"
          value="30"
        >
          <template v-slot:default="{ value }">
            <strong>{{ value }}%</strong>
          </template>
        </v-progress-linear>
      </v-col>
    </v-row>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    query: false,
  }),
};
</script>

Here, we simply display the progress bar value as a percentage:

Using a Progress Bar as a Loading Indicator

One instance where the progress linear component is useful is in communicating to the user that a response is pending. Like when fetching the user’s photos from a server in a sample photo app.

<template>
  <v-app>
    <v-app-bar app color="primary" dark>
      <v-app-bar-nav-icon></v-app-bar-nav-icon>
      <v-toolbar-title>Photos</v-toolbar-title>
      <v-spacer></v-spacer>
      <v-btn icon>
        <v-icon>mdi-share-variant</v-icon>
      </v-btn>
      <v-btn icon>
        <v-icon>mdi-magnify</v-icon>
      </v-btn>
      <v-btn icon>
        <v-icon>mdi-dots-vertical</v-icon>
      </v-btn>
    </v-app-bar>
    <v-container style="flex: 1">
      <v-row class="fill-height" align-content="center" justify="center">
        <v-col class="text-subtitle-1 text-center" cols="12">
          Getting your photos
        </v-col>
        <v-col cols="6">
          <v-progress-linear
            color="primary"
            indeterminate
            rounded
            height="6"
          ></v-progress-linear>
        </v-col>
      </v-row>
    </v-container>
  </v-app>
</template>

<script>
export default {
  name: 'App',

};
</script>

Using a Progress Bar as an App Bar Loader

A progress bar can also function as an app bar loader. With the absolute and bottom props, we can position it at the bottom of the app bar and control its visibility with the active prop:

<template>
  <v-app>
    <v-system-bar>
      <v-spacer></v-spacer>
      <v-icon>mdi-square</v-icon>
      <v-icon>mdi-circle</v-icon>
      <v-icon>mdi-triangle</v-icon>
    </v-system-bar>

    <v-app-bar app color>
      <v-btn icon>
        <v-icon>mdi-arrow-left</v-icon>
      </v-btn>

      <v-toolbar-title>Books</v-toolbar-title>

      <v-progress-linear
        :active="loading"
        :indeterminate="loading"
        absolute
        bottom
        color="indigo"
      ></v-progress-linear>

      <v-spacer></v-spacer>

      <v-btn icon>
        <v-icon>mdi-magnify</v-icon>
      </v-btn>

      <v-btn icon>
        <v-icon>mdi-dots-vertical</v-icon>
      </v-btn>
    </v-app-bar>

    <v-container style="flex: 1">
      <v-row class="fill-height" align="center" justify="center">
        <v-scale-transition>
          <div v-if="!loading" class="text-center">
            <v-btn color="indigo" dark @click="loading = true">
              Start loading
            </v-btn>
          </div>
        </v-scale-transition>
      </v-row>
    </v-container>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    loading: false,
  }),
  watch: {
    loading(val) {
      if (!val) return;

      setTimeout(() => (this.loading = false), 3000);
    },
  },
};
</script>

Conclusion

A progress bar conveys information to the user about the current progress of an ongoing event in an application. Use the Vuetify progress linear component (v-progress-linear) and its various props to create and customize horizontal linear progress bars.

A menu is a versatile component in a user interface. It shows a popover that can serve various functions, such as displaying a list of options. They can be used with other components like a toolbar, app bar, or a button. In this article, we’re to learn how to create and customize a menu in Vuetify.

The v-menu Component

Vuetify provides the v-menu component for creating a menu. We use the activator slot to set the component that will activate the menu when clicked. We set it to a button in this example:

<template>
  <v-app>
    <div class="text-center ma-4">
      <v-menu offset-y>
        <template v-slot:activator="{ on, attrs }">
          <v-btn color="primary" dark v-bind="attrs" v-on="on">
            Dropdown
          </v-btn>
        </template>
        <v-list>
          <v-list-item v-for="index in 4" :key="index">
            <v-list-item-title>Item {{ index }}</v-list-item-title>
          </v-list-item>
        </v-list>
      </v-menu>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Clicking the button will display the popover menu:

Creating an Absolute Menu in Vuetify

We can place a menu on the top of the element in the activator slot with the absolute prop.

<template>
  <v-app>
    <div class="d-flex justify-center ma-4">
      <v-menu offset-y absolute>
        <template v-slot:activator="{ on, attrs }">
          <v-card
            class="portrait"
            img="https://picsum.photos/1920/1080?random"
            height="300"
            width="600"
            v-bind="attrs"
            v-on="on"
          ></v-card>
        </template>
        <v-list>
          <v-list-item v-for="index in 4" :key="index">
            <v-list-item-title>Item {{ index }}</v-list-item-title>
          </v-list-item>
        </v-list>
      </v-menu>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Absolute Menu without Activator

We can also use a menu without an activator by using absolute together with the position-x and position-y props. This is useful for creating a context menu:

<template>
  <v-app>
    <div>
      <div class="d-flex justify-center ma-4">
        <v-card
          :ripple="false"
          class="portrait"
          img="https://picsum.photos/1920/1080?random"
          height="300"
          width="600"
          @contextmenu="show"
        ></v-card>
      </div>
      <v-menu
        v-model="showMenu"
        :position-x="x"
        :position-y="y"
        absolute
        offset-y
      >
        <v-list>
          <v-list-item v-for="index in 4" :key="index">
            <v-list-item-title>Option {{ index }}</v-list-item-title>
          </v-list-item>
        </v-list>
      </v-menu>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    showMenu: false,
    x: 0,
    y: 0,
  }),

  methods: {
    show(e) {
      e.preventDefault();
      this.showMenu = false;
      this.x = e.clientX;
      this.y = e.clientY;
      this.$nextTick(() => {
        this.showMenu = true;
      });
    },
  },
};
</script>

Closing the Menu on Click

The close-on-click prop determines whether the menu closes when it loses focus or not.

<template>
  <v-app>
    <div class="text-center ma-4">
      <v-menu offset-y :close-on-click="true">
        <template v-slot:activator="{ on, attrs }">
          <v-btn color="primary" dark v-bind="attrs" v-on="on">
            Dropdown
          </v-btn>
        </template>
        <v-list>
          <v-list-item v-for="index in 4" :key="index">
            <v-list-item-title>Item {{ index }}</v-list-item-title>
          </v-list-item>
        </v-list>
      </v-menu>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Here close-on-click is set to true, so clicking on another element will close the menu:

If we set it to false:

<template>
  <v-app>
    <div class="text-center ma-4">
      <v-menu offset-y :close-on-click="false">
        <template v-slot:activator="{ on, attrs }">
          <v-btn color="primary" dark v-bind="attrs" v-on="on">
            Dropdown
          </v-btn>
        </template>
        <v-list>
          <v-list-item v-for="index in 4" :key="index">
            <v-list-item-title>Item {{ index }}</v-list-item-title>
          </v-list-item>
        </v-list>
      </v-menu>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

It will remain open even when we click on another element or remove its focus:

Close Menu on Content Click

We can use the close-on-content-click prop to determine whether the menu should be closed when its content is clicked.

Setting close-on-content-click to true:

<template>
  <v-app>
    <div class="text-center ma-4">
      <v-menu offset-y :close-on-content-click="true">
        <template v-slot:activator="{ on, attrs }">
          <v-btn color="purple accent-4" dark v-bind="attrs" v-on="on">
            Dropdown
          </v-btn>
        </template>
        <v-list>
          <v-list-item v-for="index in 4" :key="index">
            <v-list-item-title>Item {{ index }}</v-list-item-title>
          </v-list-item>
        </v-list>
      </v-menu>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Setting close-on-content-click to false:

<template>
  <v-app>
    <div class="text-center ma-4">
      <v-menu offset-y :close-on-content-click="false">
        <template v-slot:activator="{ on, attrs }">
          <v-btn color="purple accent-4" dark v-bind="attrs" v-on="on">
            Dropdown
          </v-btn>
        </template>
        <v-list>
          <v-list-item v-for="index in 4" :key="index">
            <v-list-item-title>Item {{ index }}</v-list-item-title>
          </v-list-item>
        </v-list>
      </v-menu>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Disabled Menu

We can prevent a menu from being opened with the disabled prop:

<template>
  <v-app>
    <div class="text-center ma-4">
      <v-menu offset-y disabled>
        <template v-slot:activator="{ on, attrs }">
          <v-btn color="green" dark v-bind="attrs" v-on="on"> Dropdown </v-btn>
        </template>
        <v-list>
          <v-list-item v-for="index in 4" :key="index">
            <v-list-item-title>Item {{ index }}</v-list-item-title>
          </v-list-item>
        </v-list>
      </v-menu>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Menu Offset

Offset X

We can use the offset-x prop to offset the menu by the X-axis to make the activator visible.

<template>
  <v-app>
    <div class="text-center ma-4">
      <v-menu offset-x>
        <template v-slot:activator="{ on, attrs }">
          <v-btn color="primary" dark v-bind="attrs" v-on="on">
            Dropdown
          </v-btn>
        </template>
        <v-list>
          <v-list-item v-for="index in 4" :key="index">
            <v-list-item-title>Item {{ index }}</v-list-item-title>
          </v-list-item>
        </v-list>
      </v-menu>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Offset Y

We can also offset the menu by the Y-axis to make the activator visible.

<template>
  <v-app>
    <div class="text-center ma-4">
      <v-menu offset-y>
        <template v-slot:activator="{ on, attrs }">
          <v-btn color="primary" dark v-bind="attrs" v-on="on">
            Dropdown
          </v-btn>
        </template>
        <v-list>
          <v-list-item v-for="index in 4" :key="index">
            <v-list-item-title>Item {{ index }}</v-list-item-title>
          </v-list-item>
        </v-list>
      </v-menu>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Offset X and Offset Y

We can also combine these two props:

<template>
  <v-app>
    <div class="text-center ma-4">
      <v-menu offset-x offset-y>
        <template v-slot:activator="{ on, attrs }">
          <v-btn color="primary" dark v-bind="attrs" v-on="on">
            Dropdown
          </v-btn>
        </template>
        <v-list>
          <v-list-item v-for="index in 4" :key="index">
            <v-list-item-title>Item {{ index }}</v-list-item-title>
          </v-list-item>
        </v-list>
      </v-menu>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Open Menu on Hover

Setting the open-on-hover prop to true will make the menu open when its activator is hovered over.

<template>
  <v-app>
    <div class="text-center ma-4">
      <v-menu open-on-hover offset-y>
        <template v-slot:activator="{ on, attrs }">
          <v-btn color="teal" dark v-bind="attrs" v-on="on"> Dropdown </v-btn>
        </template>
        <v-list>
          <v-list-item v-for="index in 4" :key="index">
            <v-list-item-title>Item {{ index }}</v-list-item-title>
          </v-list-item>
        </v-list>
      </v-menu>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Creating a Rounded Menu in Vuetify

The rounded prop allows us to customize the border-radius of a menu.

Setting it to 0 will remove the border-radius:

<template>
  <v-app>
    <div class="text-center ma-4">
      <v-menu offset-y rounded="0">
        <template v-slot:activator="{ on, attrs }">
          <v-btn color="blue" dark v-bind="attrs" v-on="on">
            Removed Radius
          </v-btn>
        </template>
        <v-list>
          <v-list-item v-for="index in 4" :key="index">
            <v-list-item-title>Item {{ index }}</v-list-item-title>
          </v-list-item>
        </v-list>
      </v-menu>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

We can give the menu a large border-radius by setting rounded to true:

<template>
  <v-app>
    <div class="text-center ma-4">
      <v-menu offset-y rounded="lg">
        <template v-slot:activator="{ on, attrs }">
          <v-btn color="indigo" dark v-bind="attrs" v-on="on">
            Large Radius</v-btn
          >
        </template>
        <v-list>
          <v-list-item v-for="index in 4" :key="index">
            <v-list-item-title>Item {{ index }}</v-list-item-title>
          </v-list-item>
        </v-list>
      </v-menu>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

We can also specify a custom border-radius, for example:

<template>
  <v-app>
    <div class="text-center ma-4">
      <v-menu offset-y rounded="b-xl">
        <template v-slot:activator="{ on, attrs }">
          <v-btn color="red" dark v-bind="attrs" v-on="on">
            Custom Radius</v-btn
          >
        </template>
        <v-list>
          <v-list-item v-for="index in 4" :key="index">
            <v-list-item-title>Item {{ index }}</v-list-item-title>
          </v-list-item>
        </v-list>
      </v-menu>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Using a Menu with a Tooltip

We can also display a tooltip for a menu. We do this by nesting activator slots with the v-slot syntax and attaching the props of the slots to the same activator component (a button in this case).

<template>
  <v-app>
    <div class="text-center ma-4">
      <v-menu>
        <template v-slot:activator="{ on: menu, attrs }">
          <v-tooltip bottom>
            <template v-slot:activator="{ on: tooltip }">
              <v-btn
                color="primary"
                dark
                v-bind="attrs"
                v-on="{ ...tooltip, ...menu }"
              >
                Dropdown w/ Tooltip</v-btn
              >
            </template>
            <span>This is a tooltip</span>
          </v-tooltip>
        </template>
        <v-list>
          <v-list-item v-for="index in 4" :key="index">
            <v-list-item-title>Item {{ index }}</v-list-item-title>
          </v-list-item>
        </v-list>
      </v-menu>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Custom Menu Transitions in Vuetify

We can also customize the transition that the menu will use to open and close. Vuetify comes with three standard transitions: scale, slide-x and slide-y.

Scale Transition

The scale-transition makes the menu grow in size when opening, and shrink back when closing:

<template>
  <v-app>
    <div class="text-center ma-4">
      <v-menu transition="scale-transition" origin="center center" bottom>
        <template v-slot:activator="{ on, attrs }">
          <v-btn color="primary" dark v-bind="attrs" v-on="on">
            Scale Transition</v-btn
          >
        </template>
        <v-list>
          <v-list-item v-for="index in 4" :key="index">
            <v-list-item-title>Item {{ index }}</v-list-item-title>
          </v-list-item>
        </v-list>
      </v-menu>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Slide X Transition

The slide-x-transition makes the menu slide in from the left when opening, and slide back out when closing:

<template>
  <v-app>
    <div class="text-center ma-4">
      <v-menu transition="slide-x-transition" bottom right>
        <template v-slot:activator="{ on, attrs }">
          <v-btn color="primary" dark v-bind="attrs" v-on="on">
            Slide X Transition</v-btn
          >
        </template>
        <v-list>
          <v-list-item v-for="index in 4" :key="index">
            <v-list-item-title>Item {{ index }}</v-list-item-title>
          </v-list-item>
        </v-list>
      </v-menu>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Slide Y Transition

The slide-y-transition makes the menu slide in from the top when opening, and slide back out when closing:

<template>
  <v-app>
    <div class="text-center ma-4">
      <v-menu transition="slide-y-transition" bottom>
        <template v-slot:activator="{ on, attrs }">
          <v-btn color="primary" dark v-bind="attrs" v-on="on">
            Slide X Transition</v-btn
          >
        </template>
        <v-list>
          <v-list-item v-for="index in 4" :key="index">
            <v-list-item-title>Item {{ index }}</v-list-item-title>
          </v-list-item>
        </v-list>
      </v-menu>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Using a Menu with an App Bar

We can use a menu with a toolbar or app bar:

<template>
  <v-app>
    <v-app-bar app color="deep-purple accent-4" dark>
      <v-app-bar-nav-icon> </v-app-bar-nav-icon>
      <v-toolbar-title>Coding Beauty</v-toolbar-title>
      <v-spacer></v-spacer>
      <v-btn icon> <v-icon> mdi-heart </v-icon> </v-btn>
      <v-btn icon>
        <v-icon>mdi-magnify</v-icon>
      </v-btn>
      <v-menu left bottom>
        <template v-slot:activator="{ on, attrs }">
          <v-btn icon v-bind="attrs" v-on="on">
            <v-icon>mdi-dots-vertical</v-icon>
          </v-btn>
        </template>

        <v-list>
          <v-list-item v-for="n in 4" :key="n" @click="() => {}">
            Option {{ n }}
          </v-list-item>
        </v-list>
      </v-menu>
    </v-app-bar>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Conclusion

A menu is a versatile user interface component in a user interface that shows a popover that we can use for a variety of purposes. It can work with a button, a toolbar or an app bar. Vuetify provides the v-menu component for creating and customizing menus.

An app bar is an important part of every user interface and is typically the primary source of site navigation. Like a toolbar, it is displayed at the top of the screen and can be combined with a navigation drawer or tabs. In this article, we’re going to learn how to create and customize app bars with Vuetify.

The v-app-bar Component

Vuetify provides the v-app-bar component for creating app bars. We use the app prop on the component to make Vuetify consider the app bar when dynamically sizing other components, such as v-main.

<template>
  <v-app>
    <v-app-bar app></v-app-bar>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

App Bar Title

We can use the v-toolbar-title component to set the app bar title.

<template>
  <v-app>
    <v-app-bar app>
      <v-toolbar-title>Coding Beauty</v-toolbar-title>
    </v-app-bar>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Note: While we could use the v-app-bar-title component to set the app bar title, the Vuetify team does not recommend using it without the shrink-on-scroll prop (discussed later in this article), as it would add an unnecessary resize watcher and additional calculations.

App Bar Nav Icon

v-app-bar-nav-icon is a styled icon button component created specifically for use with a toolbar or app bar. An app bar nav icon is typically placed on the left side of the toolbar or app bar as a hamburger menu, and is often used to control the state of a navigation drawer. We can customize the icon and function of this component with the default slot.

<template>
  <v-app>
    <v-app-bar app>
      <v-app-bar-nav-icon> </v-app-bar-nav-icon>
      <v-toolbar-title>Coding Beauty</v-app-bar-title>
    </v-app-bar>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

App Bar Colors

The app bar component comes with the color prop for customizing the color of the app bar. The dark prop makes the color of the text white

<template>
  <v-app>
    <v-app-bar app color="green" dark>
      <v-app-bar-nav-icon> </v-app-bar-nav-icon>
      <v-app-bar-title>Coding Beauty</v-app-bar-title>
    </v-app-bar>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Collapsed App Bar

Setting the collapse prop to true on the v-app-bar will collapse the app bar at all times:

<template>
  <v-app>
    <v-app-bar app color="primary" dark collapse>
      <v-app-bar-nav-icon> </v-app-bar-nav-icon>
      <v-app-bar-title>Collapsing Bar</v-app-bar-title>
    </v-app-bar>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Collapse on Scroll

We can decide to use the collapse-on-scroll prop to collapse the app bar only when the user scrolls.

<template>
  <v-app>
    <v-app-bar app color="primary" dark collapse-on-scroll>
      <v-app-bar-nav-icon> </v-app-bar-nav-icon>
      <v-toolbar-title>Collapsing Bar</v-toolbar-title>
    </v-app-bar>
    <v-sheet>
      <v-container style="height: 1000px"> </v-container>
    </v-sheet>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

App Bar Actions

We can add functionality to the app bar that we want to be easily accessible to the user with icon buttons.

<template>
  <v-app>
    <v-app-bar app color="yellow accent-3">
      <v-app-bar-nav-icon> </v-app-bar-nav-icon>
      <v-toolbar-title>Coding Beauty</v-toolbar-title>
      <v-spacer></v-spacer>
      <v-btn icon> <v-icon> mdi-heart </v-icon> </v-btn>
      <v-btn icon>
        <v-icon>mdi-magnify</v-icon>
      </v-btn>
    </v-app-bar>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

App Bar Menu

We can also extend the functionality of the app bar with a menu component (v-menu).

<template>
  <v-app>
    <v-app-bar app color="deep-purple accent-4" dark>
      <v-app-bar-nav-icon> </v-app-bar-nav-icon>
      <v-toolbar-title>Coding Beauty</v-toolbar-title>
      <v-spacer></v-spacer>
      <v-btn icon> <v-icon> mdi-heart </v-icon> </v-btn>
      <v-btn icon>
        <v-icon>mdi-magnify</v-icon>
      </v-btn>
      <v-menu left bottom>
        <template v-slot:activator="{ on, attrs }">
          <v-btn icon v-bind="attrs" v-on="on">
            <v-icon>mdi-dots-vertical</v-icon>
          </v-btn>
        </template>

        <v-list>
          <v-list-item v-for="n in 4" :key="n" @click="() => {}">
            Option {{ n }}
          </v-list-item>
        </v-list>
      </v-menu>
    </v-app-bar>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Clicking the menu icon button will display the popup containing the options we added:

Dense App Bar

We can use the dense prop to make an app bar dense. A dense app bar has a lower height than a regular one.

<template>
  <v-app>
    <v-app-bar app color="deep-purple accent-4" dark dense>
      <v-app-bar-nav-icon> </v-app-bar-nav-icon>
      <v-toolbar-title>Coding Beauty</v-toolbar-title>
      <v-spacer></v-spacer>
      <v-btn icon> <v-icon> mdi-heart </v-icon> </v-btn>
      <v-btn icon>
        <v-icon>mdi-magnify</v-icon>
      </v-btn>
      <v-menu left bottom>
        <template v-slot:activator="{ on, attrs }">
          <v-btn icon v-bind="attrs" v-on="on">
            <v-icon>mdi-dots-vertical</v-icon>
          </v-btn>
        </template>

        <v-list>
          <v-list-item v-for="n in 4" :key="n" @click="() => {}">
            Option {{ n }}
          </v-list-item>
        </v-list>
      </v-menu>
    </v-app-bar>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Elevate on Scroll

When we set the elevate-on-scroll prop to true, the app bar will rest at an elevation of 0dp until the user begins to scroll down. The elevation raises to 4dp once scrolling begins.

<template>
  <v-app>
    <v-app-bar app color="white" elevate-on-scroll>
      <v-app-bar-nav-icon> </v-app-bar-nav-icon>
      <v-toolbar-title>Coding Beauty</v-toolbar-title>
      <v-spacer></v-spacer>
      <v-btn icon> <v-icon> mdi-heart </v-icon> </v-btn>
      <v-btn icon>
        <v-icon>mdi-magnify</v-icon>
      </v-btn>
      <v-menu left bottom>
        <template v-slot:activator="{ on, attrs }">
          <v-btn icon v-bind="attrs" v-on="on">
            <v-icon>mdi-dots-vertical</v-icon>
          </v-btn>
        </template>

        <v-list>
          <v-list-item v-for="n in 4" :key="n" @click="() => {}">
            Option {{ n }}
          </v-list-item>
        </v-list>
      </v-menu>
    </v-app-bar>
    <v-sheet>
      <v-container style="height: 1000px"> </v-container>
    </v-sheet>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Extending the App Bar with Tabs

We can extend the app bar with tabs by including the tabs in the extension slot of v-app-bar:

<template>
  <v-app>
    <v-app-bar app color="primary" dark>
      <v-app-bar-nav-icon> </v-app-bar-nav-icon>
      <v-toolbar-title>Coding Beauty</v-toolbar-title>
      <v-spacer></v-spacer>
      <v-btn icon>
        <v-icon>mdi-magnify</v-icon>
      </v-btn>
      <v-menu left bottom>
        <template v-slot:activator="{ on, attrs }">
          <v-btn icon v-bind="attrs" v-on="on">
            <v-icon>mdi-dots-vertical</v-icon>
          </v-btn>
        </template>
      </v-menu>

      <template v-slot:extension>
        <v-tabs align-with-title>
          <v-tab>Tab 1</v-tab>
          <v-tab>Tab 2</v-tab>
          <v-tab>Tab 3</v-tab>
        </v-tabs>
      </template>
    </v-app-bar>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Prominent App Bar

Setting the prominent prop to true will increase its height.

<template>
  <v-app>
    <v-app-bar app color="primary" dark prominent>
      <v-app-bar-nav-icon> </v-app-bar-nav-icon>
      <v-toolbar-title>Title</v-toolbar-title>
      <v-spacer></v-spacer>
      <v-btn icon>
        <v-icon>mdi-magnify</v-icon>
      </v-btn>
      <v-menu left bottom>
        <template v-slot:activator="{ on, attrs }">
          <v-btn icon v-bind="attrs" v-on="on">
            <v-icon>mdi-dots-vertical</v-icon>
          </v-btn>
        </template>
      </v-menu>

      <template v-slot:extension>
        <v-tabs align-with-title>
          <v-tab>Tab 1</v-tab>
          <v-tab>Tab 2</v-tab>
          <v-tab>Tab 3</v-tab>
        </v-tabs>
      </template>
    </v-app-bar>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Shrink on Scroll

With the shrink-on-scroll prop, we can a prominent app bar reduce in height as the user scrolls down. This allows for a smooth transition to taking up less visual space when the user is scrolling through content.

<template>
  <v-app>
    <v-app-bar app color="primary" dark prominent shrink-on-scroll>
      <v-app-bar-nav-icon> </v-app-bar-nav-icon>
      <v-toolbar-title>Title</v-toolbar-title>
      <v-spacer></v-spacer>
      <v-btn icon>
        <v-icon>mdi-magnify</v-icon>
      </v-btn>
      <v-menu left bottom>
        <template v-slot:activator="{ on, attrs }">
          <v-btn icon v-bind="attrs" v-on="on">
            <v-icon>mdi-dots-vertical</v-icon>
          </v-btn>
        </template>
      </v-menu>

      <template v-slot:extension>
        <v-tabs align-with-title>
          <v-tab>Tab 1</v-tab>
          <v-tab>Tab 2</v-tab>
          <v-tab>Tab 3</v-tab>
        </v-tabs>
      </template>
    </v-app-bar>
    <v-sheet>
      <v-container style="height: 1000px"></v-container>
    </v-sheet>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

App Bar Images

We can display background images on the app bar with the src prop. When we set an image, the color prop acts as a fallback color that the app bar will display when the image has not yet loaded or fails to load.

<template>
  <v-app>
    <v-app-bar
      app
      color="primary"
      dark
      prominent
      src="https://picsum.photos/1920/1080?random"
    >
      <v-app-bar-nav-icon> </v-app-bar-nav-icon>
      <v-toolbar-title>Title</v-toolbar-title>
      <v-spacer></v-spacer>
      <v-btn icon>
        <v-icon>mdi-magnify</v-icon>
      </v-btn>
      <v-menu left bottom>
        <template v-slot:activator="{ on, attrs }">
          <v-btn icon v-bind="attrs" v-on="on">
            <v-icon>mdi-dots-vertical</v-icon>
          </v-btn>
        </template>
      </v-menu>

      <template v-slot:extension>
        <v-tabs align-with-title>
          <v-tab>Tab 1</v-tab>
          <v-tab>Tab 2</v-tab>
          <v-tab>Tab 3</v-tab>
        </v-tabs>
      </template>
    </v-app-bar>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Fade Image on Scroll

We might want to make the background image on the app bar fade as the user scrolls down. We can do this with the fade-img-on-scroll prop. As we scroll, the image reduces in opacity until it totally fades away and we can only see the background color.

<template>
  <v-app>
    <v-app-bar
      app
      color="grey"
      dark
      prominent
      src="https://picsum.photos/1920/1080?random"
      fade-img-on-scroll
    >
      <v-app-bar-nav-icon> </v-app-bar-nav-icon>
      <v-app-bar-title>Title</v-app-bar-title>
      <v-spacer></v-spacer>
      <v-btn icon>
        <v-icon>mdi-magnify</v-icon>
      </v-btn>
      <v-menu left bottom>
        <template v-slot:activator="{ on, attrs }">
          <v-btn icon v-bind="attrs" v-on="on">
            <v-icon>mdi-dots-vertical</v-icon>
          </v-btn>
        </template>
      </v-menu>

      <template v-slot:extension>
        <v-tabs align-with-title>
          <v-tab>Tab 1</v-tab>
          <v-tab>Tab 2</v-tab>
          <v-tab>Tab 3</v-tab>
        </v-tabs>
      </template>
    </v-app-bar>
    <v-sheet>
      <v-container style="height: 1000px"> </v-container>
    </v-sheet>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Hide on Scroll

We can hide the app bar when the user starts to scroll with the hide-on-scroll prop.

<template>
  <v-app>
    <v-app-bar app color="teal" dark hide-on-scroll>
      <v-app-bar-nav-icon> </v-app-bar-nav-icon>
      <v-app-bar-title>Title</v-app-bar-title>
      <v-spacer></v-spacer>
      <v-btn icon>
        <v-icon>mdi-magnify</v-icon>
      </v-btn>
      <v-menu left bottom>
        <template v-slot:activator="{ on, attrs }">
          <v-btn icon v-bind="attrs" v-on="on">
            <v-icon>mdi-dots-vertical</v-icon>
          </v-btn>
        </template>
      </v-menu>
    </v-app-bar>
    <v-sheet>
      <v-container style="height: 1000px"> </v-container>
    </v-sheet>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Inverted Scroll

When the inverted-scroll prop is set to true, the app bar will hide until the user scrolls past the designated threshold. Once past the threshold, the app bar will continue to display until the user scrolls up past the threshold. If the scroll-treshold prop is not set, a default value of 0 will be used.

<template>
  <v-app>
    <v-app-bar app color="primary" dark inverted-scroll>
      <v-app-bar-nav-icon> </v-app-bar-nav-icon>
      <v-app-bar-title>Coding Beauty</v-app-bar-title>
      <v-spacer></v-spacer>
      <v-btn icon>
        <v-icon>mdi-magnify</v-icon>
      </v-btn>
      <v-menu left bottom>
        <template v-slot:activator="{ on, attrs }">
          <v-btn icon v-bind="attrs" v-on="on">
            <v-icon>mdi-dots-vertical</v-icon>
          </v-btn>
        </template>
      </v-menu>
    </v-app-bar>
    <v-sheet>
      <v-container style="height: 1000px"> </v-container>
    </v-sheet>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Using an App Bar with a Navigation Drawer

We can add a navigation drawer to our user interface and use the functional v-nav-bar-icon component on the app bar to toggle its visibility.

<template>
  <v-app>
    <v-app-bar app color="green" dark>
      <v-app-bar-nav-icon @click="drawer = true"> </v-app-bar-nav-icon>
      <v-toolbar-title>Coding Beauty</v-toolbar-title>
    </v-app-bar>
    <v-navigation-drawer v-model="drawer" absolute temporary>
      <v-list nav dense>
        <v-list-item-group
          v-model="group"
          active-class="deep-purple--text text--accent-4"
        >
          <v-list-item>
            <v-list-item-icon>
              <v-icon>mdi-home</v-icon>
            </v-list-item-icon>
            <v-list-item-title>Home</v-list-item-title>
          </v-list-item>

          <v-list-item>
            <v-list-item-icon>
              <v-icon>mdi-account</v-icon>
            </v-list-item-icon>
            <v-list-item-title>Account</v-list-item-title>
          </v-list-item>
        </v-list-item-group>
      </v-list>
    </v-navigation-drawer>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    drawer: false,
    group: null,
  }),
};
</script>

Conclusion

We can add an app bar to a user interface for quick and easy navigation. Vuetify provides the v-app-bar component for creating and customizing the behaviour and appearance of an app bar.

Every user interface contains some text. Different texts have different styles according to their purpose in the UI. Vuetify provides various classes that we can use to control various text properties such as size, alignment, wrapper, overflow and transforms. We’re going to learn about these typography helper classes in this article.

Font Size

Vuetify comes with classes for modifying the font size and style of a text. They are of the following formats:

• .text-{value} for the xs breakpoint.
• .text-{breakpoint}-{value} for the sm, md, lg and xl breakpoints.

The value can be any of the following:

• h1
• h2
• h3
• h4
• h5
• h6
• subtitle-1
• subtitle-2
• body-1
• body-2
• button
• caption
• overline

<template>
  <v-app>
    <div class="ma-4">
      <div class="text-h1">Heading 1</div>
      <div class="text-h2">Heading 2</div>
      <div class="text-h3">Heading 3</div>
      <div class="text-h4">Heading 4</div>
      <div class="text-h5">Heading 5</div>
      <div class="text-subtitle-1">Subtitle 1</div>
      <div class="text-subtitle-2">Subtitle 2</div>
      <div class="text-body-1">Body 1</div>
      <div class="text-body-2">Body 2</div>
      <div class="text-button">Button</div>
      <div class="text-caption">Caption</div>
      <div class="text-overline">Overline</div>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Font Emphasis

Vuetify also provides typography classes that control the font emphasis of the text. Material Design supports italicized text and font weights of 100, 300, 400, 500, 700 and 900.

<template>
  <v-app>
    <div class="ma-4">
      <div class="font-weight-black">Black text</div>
      <div class="font-weight-bold">Bold text</div>
      <div class="font-weight-medium">Medium weight text</div>
      <div class="font-weight-regular">Normal weight text</div>
      <div class="font-weight-light">Light weight text</div>
      <div class="font-weight-thin">Thin weight text</div>
      <div class="font-italic">Italic text</div>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Text Alignment

text-left, text-center, and text-right are typography classes used to set the alignment of text:

<template>
  <v-app>
    <div class="ma-4">
      <p class="text-left">Left aligned text on all viewport sizes.</p>
      <p class="text-center">Center aligned text on all viewport sizes.</p>
      <p class="text-right">Right aligned text on all viewport sizes.</p>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Just like with font weights, Vuetify also comes with typography classes for targeting certain viewport width ranges. They include:

• text-sm-{value}
• text-md-{value}
• text-lg-{value}
• text-xl-{value}

value can be left, center or right.

Text Decoration

In addition, Vuetify has typography classes for adding text decorations. There are of the form text-decoration-{value}, where value can be none, overline, underline or line-through.

<template>
  <v-app>
    <div class="ma-4">
      <p class="text-decoration-overline">Overline text</p>
      <p class="text-decoration-underline">Underline text</p>
      <p class="text-decoration-line-through">Line-through text</p>
      <a href="#" class="text-decoration-none">Non-underlined link</a>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Text Opacity

Opacity typography helper classes are another handy way of adjusting text emphasis with Vuetify. text--primary has the same opacity as default text, text--secondary is used for hints and helper text. De-emphasize text with text--disabled.

<template>
  <v-app>
    <div class="ma-4">
      <p class="text--primary">
        High-emphasis has an opacity of 87% in light theme and 100% in dark.
      </p>
      <p class="text--secondary">
        Medium-emphasis text and hint text have opacities of 60% in light theme
        and 70% in dark.
      </p>
      <p class="text--disabled">
        Disabled text has an opacity of 38% in light theme and 50% in dark.
      </p>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Text Transform

We can transform text with Vuetify using the text capitalization typography classes. They are text-lowercase, text-uppercase, and text-capitalize.

<template>
  <v-app>
    <div class="ma-4">
      <p class="text-lowercase">Lowercased text</p>
      <p class="text-uppercase">Uppercased text</p>
      <p class="text-capitalize">CapiTaliZed text</p>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Wrapping and Overflow

The text-no-wrap typography class allows us to prevent text wrapping:

<template>
  <v-app>
    <div class="text-no-wrap blue ma-4" style="width: 8rem">
      This text should overflow the parent.
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Summary

Typography is an important aspect of every user interface. Vuetify provides various helper classes to allow us easily modify text properties.

We use an alert to pass on important information to users by using contextual icons and colors. The icon and color match the type of message it conveys to the user. In this article, we’re going to learn how to create and customize alert notifications with the Vuetify alert component.

The Vuetify Alert Component (v-alert)

Vuetify provides the v-alert component for creating alerts:

<template>
  <v-app>
    <div class="d-flex justify-center ma-4">
      <v-alert> Alert Component </v-alert>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Using v-alert without any props creates a simple alert containing the text, without any color, border or icon:

Vuetify Alert Colors

The color prop of v-alert allows us to customize the color of an alert component.

<template>
  <v-app>
    <div class="d-flex justify-center ma-4">
      <v-col sm="6">
        <v-alert color="indigo" dark> Alert Component </v-alert>
      </v-col>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Vuetify Alert Border

The border prop adds a border to one of the 4 sides of the alert. They are four possible values for each of the sides: top, bottom, left, and right.

<template>
  <v-app>
    <div class="d-flex justify-center ma-4">
      <v-col sm="6">
        <v-alert border="top" color="red lighten-2" dark>
          I'm an alert with a top border and red color
        </v-alert>
        <v-alert border="right" color="green" dark>
          I'm an alert with a right border and green color
        </v-alert>
        <v-alert border="bottom" color="pink darken-1" dark>
          I'm an alert with a bottom border and pink color
        </v-alert>
        <v-alert border="left" color="indigo" dark>
          I'm an alert with a left border and indigo color
        </v-alert>
      </v-col>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Vuetify Alert Colored Border

The colored-prop will remove the alert background in order to emphasize the border, whose color is set to the value of the color prop:

<template>
  <v-app>
    <div class="d-flex justify-center ma-4">
      <v-col sm="6">
        <v-alert border="left" color="indigo" colored-border elevation="2">
          An alert with a colored border
        </v-alert>
      </v-col>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Dense Alert

Setting the dense prop to true on the v-alert will make it more compact by decreasing its height.

<template>
  <v-app>
    <div class="d-flex justify-center ma-4">
      <v-col sm="6">
        <v-alert dense type="info">
          Dense alert of type info
        </v-alert>
      </v-col>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

When a border is set, the border thickness will be decreased to stay consistent with the dense style:

<template>
  <v-app>
    <div class="d-flex justify-center ma-4">
      <v-col sm="6">
        <v-alert dense type="info" border="right">
          Dense alert of type info
        </v-alert>
      </v-col>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Vuetify Alert Dismissable

The dimissable prop adds a close icon button at the end of the alert component.

<template>
  <v-app>
    <div class="d-flex justify-center ma-4">
      <v-col sm="6">
        <v-alert border="top" color="green" dismissible dark>
          Dismissable alert
        </v-alert>
      </v-col>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Clicking the close button will set the alert value to false, which will hide the alert:

Vuetify Alert v-model

We can also directly control the visibility of the alert from code by using v-model to create a two-way binding between a variable and the alert value.

To see how to do this in practice, let’s create a button below the now hidden alert from our previous code sample. We’ll also set up the two-way binding between an alert variable and the visibility of the alert.

<template>
  <v-app>
    <div class="d-flex justify-center ma-4">
      <v-col sm="6">
        <v-alert border="top" color="green" dismissible dark v-model="alert">
          Dismissable alert
        </v-alert>
      </v-col>
    </div>
    <div class="d-flex justify-center ma-4">
      <v-btn color="primary" @click="alert = true">Reset</v-btn>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    alert: true,
  }),
};
</script>

Clicking the button will set alert to true, which will restore the visibility of the alert.

Alert Icons

We can include an icon at the beginning of an alert with the icon prop.

<template>
  <v-app>
    <div class="d-flex justify-center ma-4">
      <v-col sm="6">
        <v-alert border="top" color="red accent-2" dark icon="mdi-star">
          An alert with an icon
        </v-alert>
      </v-col>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Vuetify Alert Elevation

We can customize the amount of elevation an alert component has using the elevation prop. This prop can take any value between 0 and 24.

<template>
  <v-app>
    <div class="d-flex justify-center ma-4">
      <v-col sm="6">
        <v-alert border="top" color="orange" colored-border elevation="5">
          Elevated alert
        </v-alert>
      </v-col>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Vuetify Alert Outlined

Setting the outlined prop to true will display the outlined variant of an alert. This outlined style makes the alert background transparent and sets the color of its border and text to the value of the color prop.

<template>
  <v-app>
    <div class="d-flex justify-center ma-4">
      <v-col sm="6">
        <v-alert color="green" outlined> Outlined alert </v-alert>
      </v-col>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Vuetify Alert Prominent

The prominent prop makes the alert more pronounced by increasing the height and applying a halo to the icon:

<template>
  <v-app>
    <div class="d-flex justify-center ma-4">
      <v-col sm="6">
        <v-alert color="red accent-2" prominent icon="mdi-school" dark>
          Prominent alert
        </v-alert>
      </v-col>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Text Alert

The text alert variant has a reduced background opacity. We can set an alert to this alternative style with the text prop:

<template>
  <v-app>
    <div class="d-flex justify-center ma-4">
      <v-col sm="6">
        <v-alert color="teal" text> Text alert </v-alert>
      </v-col>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Vuetify Alert Shaped

Setting the shaped prop to true on an alert will add a border-radius at the top-left and bottom-right of the alert:

<template>
  <v-app>
    <div class="d-flex justify-center ma-4">
      <v-col sm="6">
        <v-alert color="blue" shaped dark> Shaped alert </v-alert>
      </v-col>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Vuetify Alert Custom Transitions

We can customize the transition an alert shows when toggling its visibility, using the transition prop. For example, in the code below we set the transition prop to scale-transition, which will make the alert display a scale transition when it is being hidden or shown.

<template>
  <v-app>
    <div class="d-flex justify-center ma-4">
      <v-btn color="primary" @click="alert = !alert"> Toggle </v-btn>
    </div>
    <div class="d-flex justify-center ma-4">
      <v-col sm="6">
        <v-alert
          color="indigo"
          dark
          transition="scale-transition"
          v-model="alert"
        >
          Shaped alert
        </v-alert>
      </v-col>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    alert: false,
  }),
};
</script>

Vuetify Alert Type

v-alert comes with a type prop which provides 4 styles that modify the icon and color of the alert. These styles are success, info, warning, and error.

<template>
  <v-app>
    <div class="d-flex justify-center ma-4">
      <v-col sm="6">
        <v-alert type="success"> I'm a success alert. </v-alert>
        <v-alert type="info"> I'm an info alert. </v-alert>
        <v-alert type="warning"> I'm a warning alert. </v-alert>
        <v-alert type="error"> I'm an error alert. </v-alert>
      </v-col>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Summary

An alert is useful for conveying important information to our users using contextual icons and colors. Vuetify provides the v-alert component for creating and customizing alerts.

Chips are used to pass on small amounts of information to users. They can be interactive and perform certain actions when clicked like buttons, or we can use them to display selected data in a select field. In this article, we’ll learn how to create and customize chips with Vuetify.

The v-chip Component

Vuetify provides the v-chip component for creating a chip.

<template>
  <v-app>
    <v-row class="ma-4" justify="center">
      <v-chip>Chip Component </v-chip>
    </v-row>
  </v-app>
</template>
<script>
export default {
  name: 'App',
};
</script>

Closable Chip

We can make a chip closable by setting the close prop to true and listening for a @click:close event.

<template>
  <v-app>
    <v-row class="ma-4" justify="center">
      <v-chip v-if="chip1" class="ma-2" close @click:close="chip1 = false"
        >Chip 1</v-chip
      >
      <v-chip v-if="chip2" class="ma-2" close @click:close="chip2 = false"
        >Chip 2</v-chip
      >
      <v-chip v-if="chip3" class="ma-2" close @click:close="chip3 = false"
        >Chip 3</v-chip
      >
    </v-row>
  </v-app>
</template>
<script>
export default {
  name: 'App',
  data: () => ({
    chip1: true,
    chip2: true,
    chip3: true,
  }),
};
</script>

In the code above, we’ve created three closable chips. Three variables control the visibility of the chips with v-if:

Clicking the close button of a chip, say “Chip 2”, will set its visibility variable to false and hide it:

Chip Colors

Like many Vuetify components, v-chip comes with the color prop, which we can use to customize its color. We can use any color from the Material Design palette.

<template>
  <v-app>
    <v-row class="ma-4" justify="center">
      <v-chip class="ma-2">Default</v-chip>
      <v-chip class="ma-2" color="green" dark>Green</v-chip>
      <v-chip class="ma-2" color="primary">Primary</v-chip>
      <v-chip class="ma-2" color="red" dark>Red</v-chip>
    </v-row>
  </v-app>
</template>
<script>
export default {
  name: 'App',
};
</script>

Draggable Chips

To make a chip draggable, set the draggable prop of the v-chip to true:

<template>
  <v-app>
    <v-row class="ma-4" justify="center">
      <v-chip class="ma-2" draggable>Draggable</v-chip>
    </v-row>
  </v-app>
</template>
<script>
export default {
  name: 'App',
};
</script>

Now it can be dragged around with the mouse:

Active Chip Filters

The v-chip component comes with a filter prop that when set to true, will show an icon on the chip if the chip is active. You can make a chip active by setting its input-value prop to true:

<template>
  <v-app>
    <v-row class="ma-4" justify="center">
      <v-chip class="ma-2" filter :input-value="true">Active Chip</v-chip>
    </v-row>
  </v-app>
</template>
<script>
export default {
  name: 'App',
};
</script>

The default icon is a checkmark, but we can customize it with the filter-icon prop.

<template>
  <v-app>
    <v-row class="ma-4" justify="center">
      <v-chip class="ma-2" filter :input-value="true" filter-icon="mdi-plus"
        >Active Chip</v-chip
      >
    </v-row>
  </v-app>
</template>
<script>
export default {
  name: 'App',
};
</script>

Label Chips

Setting the label prop to true on the v-chip will change its border-radius to that of a card component (v-card):

<template>
  <v-app>
    <v-row class="ma-4" justify="center">
      <v-chip class="ma-2" label>Label 1</v-chip>
      <v-chip class="ma-2" label color="yellow">Label 2</v-chip>
      <v-chip class="ma-2" label color="primary">Label 3</v-chip>
    </v-row>
  </v-app>
</template>
<script>
export default {
  name: 'App',
};
</script>

Button Chips

We can make a chip act like a button with the link prop:

<template>
  <v-app>
    <div class="d-flex justify-center align-center ma-4">
      <v-chip class="ma-2" link>
        Chip Component
      </v-chip>
    </div>
  </v-app>
</template>
<script>
export default {
  name: 'App',
};
</script>

Now the chip will visually respond and display a ripple when clicked.

Removing the Ripple from a Chip

Setting the ripple prop to false will remove the ripple from a chip button.

<template>
  <v-app>
    <div class="d-flex justify-center align-center ma-4">
      <v-chip class="ma-2" link :ripple="false">
        Chip Component
      </v-chip>
    </div>
  </v-app>
</template>
<script>
export default {
  name: 'App',
};
</script>

Now a ripple doesn’t show when the chip button is clicked:

Outlined Chips

We display the outlined variant of a chip by setting the outlined prop to true. Outlined chips inherit their border color from the current text color.

<template>
  <v-app>
    <v-row class="ma-4" justify="center">
      <v-chip class="ma-2" outlined color="green">Outlined 1</v-chip>
      <v-chip class="ma-2" outlined color="red">Outlined 2</v-chip>
      <v-chip class="ma-2" outlined color="indigo">Outlined 3</v-chip>
    </v-row>
  </v-app>
</template>
<script>
export default {
  name: 'App',
};
</script>

Custom Chip Sizes

The v-chip component comes with props for customizing its size. They are x-small, small, large, and x-large.

<template>
  <v-app>
    <div class="d-flex justify-center align-center ma-4">
      <v-chip class="ma-2" x-small> x-small chip </v-chip>
      <v-chip class="ma-2" small> small chip </v-chip>
      <v-chip class="ma-2"> Default </v-chip>
      <v-chip class="ma-2" large> large chip </v-chip>
      <v-chip class="ma-2" x-large> x-large chip </v-chip>
    </div>
  </v-app>
</template>
<script>
export default {
  name: 'App',
};
</script>

Chip Icons

We can display any icon from the Material Icons font library in a chip:

<template>
  <v-app>
    <div class="d-flex justify-center align-center ma-4">
      <v-chip class="ma-2" color="primary">
        Premium
        <v-icon right> mdi-star </v-icon>
      </v-chip>
      <v-chip class="ma-2" color="green accent-4" dark>
        <v-icon left> mdi-checkbox-marked-circle </v-icon>
        Confirmed
      </v-chip>
      <v-chip class="ma-2">
        <v-icon left>mdi-alarm</v-icon>
        7:00 AM
      </v-chip>
    </div>
  </v-app>
</template>
<script>
export default {
  name: 'App',
};
</script>

Summary

Chips are useful for conveying small pieces of information to users. Vuetify provides the v-chip component for creating a chip with various props for customization.

We use a date picker to let users select a date or a range of dates. In this article, we’re going to learn about the Vuetify date picker component and how it lets us create and customize date pickers.

The v-date-picker Component

Vuetify provides the v-date-picker component for creating date pickers.

<template>
  <v-app>
    <div class="d-flex justify-center mt-2">
      <v-date-picker></v-date-picker>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

The current date is shown by default:

We can select this current date if we want:

Or another date:

Two-way Binding with v-model

We can use v-model on the date picker component to set up a two-way binding between the picker and a variable. In the code below, we create a date picker and add some text below it to display the value of the date variable, which is the date selected on the picker.

<template>
  <v-app>
    <div class="d-flex justify-center mt-2">
      <v-date-picker v-model="date"></v-date-picker>
    </div>
    <div class="d-flex justify-center mt-2">Date: {{ date || 'No date' }}</div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    date: null,
  }),
};
</script>

Initially, date is null, meaning that no date has been selected. We display a text “No date” to indicate this:

Once we select a date, date is updated by the binding and the text shows it. The date is set to a string in the YYYY-MM-DD format:

Allowed Dates

We can specify allowed dates on the date picker with the allowed-dates prop. Here, we’re passing a function to it that takes the string value of the date and returns a boolean value that indicates whether the date should be allowed or not.

<template>
  <v-app>
    <div class="d-flex justify-center mt-2">
      <v-date-picker
        v-model="date"
        :allowed-dates="allowedDates"
      ></v-date-picker>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    date: null,
  }),
  methods: {
    allowedDates: (val) => parseInt(val.split('-')[2], 10) % 2 === 1,
  },
};
</script>

The function we wrote will only allow a date with an odd day to be selectable on the picker:

Date Picker Colors

We can customize the color of the date picker with the color and header-color props.

<template>
  <v-app>
    <div class="d-flex justify-center mt-2">
      <v-date-picker v-model="date" color="green"></v-date-picker>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    date: null,
  }),
};
</script>

We don’t specify a header-color in the code above, so the header color will be set to the value of the color prop:

Here we do set a header-color, and the color of the date picker reflects this:

<template>
  <v-app>
    <div class="d-flex justify-center mt-2">
      <v-date-picker
        v-model="date"
        color="green"
        header-color="primary"
      ></v-date-picker>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    date: null,
  }),
};
</script>

Date Picker Elevation

We can set the elevation of a date picker with the elevation prop. The v-date-picker component supports elevation up to a maximum of 24.

<template>
  <v-app>
    <div class="d-flex justify-center mt-2">
      <v-date-picker v-model="date" elevation="20"></v-date-picker>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    date: null,
  }),
};
</script>

Date Picker Icons

We can override the default icons the date picker uses with the year-icon, prev-icon and next-icon props.

<template>
  <v-app>
    <div class="d-flex justify-center mt-2">
      <v-date-picker
        v-model="date"
        year-icon="mdi-calendar-blank"
        prev-icon="mdi-skip-previous"
        next-icon="mdi-skip-next"
      ></v-date-picker>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    date: null,
  }),
};
</script>

Multiple Selection

We use the multiple prop to allow users to select multiple dates from the picker. When the multiple prop is set to true, the date picker component will expect the variable passed to its v-model to be an array.

<template>
  <v-app>
    <div class="d-flex justify-center mt-2">
      <v-date-picker v-model="dates" multiple></v-date-picker>
    </div>
    <div class="d-flex justify-center">Selected: {{ dates }}</div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    dates: [],
  }),
};
</script>

picker-date Sync

We can use the .sync modifier to watch the picker-date, which is the displayed month/year (depending on the picker type and active view). In the code below, we create a date picker and text below it that displays pickerDate, a variable synced to the picker-date prop using picker-date.sync.

<template>
  <v-app>
    <div class="d-flex justify-center mt-2">
      <v-date-picker
        v-model="date"
        :picker-date.sync="pickerDate"
      ></v-date-picker>
    </div>
    <div class="d-flex justify-center">Month: {{ pickerDate }}</div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    date: null,
    pickerDate: null,
  }),
};
</script>

When we change the month on the date picker (using the arrows), pickerDate is updated:

Date Picker Range

Use the range prop on a date picker component to allow users select a range of dates from it. When using the range prop, v-date-picker expects the value passed to its v-model to be an array of length 2 or empty.

<template>
  <v-app>
    <div class="d-flex justify-center mt-2">
      <v-date-picker v-model="dates" range></v-date-picker>
    </div>
    <div class="d-flex justify-center">Model: {{ dates }}</div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    dates: ['2022-03-05', '2022-03-15'],
  }),
};
</script>

We can select another date range if we want:

Readonly Date Picker

We can use the readonly prop to turn off interactivity with a date picker:

<template>
  <v-app>
    <div class="d-flex justify-center mt-2">
      <v-date-picker v-model="date" readonly></v-date-picker>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    date: null,
  }),
};
</script>

Here’s how it looks when its readonly and you try to pick another date, say March 16:

Show Current

By default, the date picker indicates the current date with the outline of a circle:

We can remove this outline by setting the show-current prop to false:

<template>
  <v-app>
    <div class="d-flex justify-center mt-2">
      <v-date-picker v-model="date" :show-current="false"></v-date-picker>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    date: null,
  }),
};
</script>

We can also make the date picker indicate another date as the current date. We do this by setting the show-current prop to a date string in the YYYY-MM-DD format:

Showing Sibling Months

By default, days from the previous and next months are not visible. Use the show-adjacent-months prop to display them:

<template>
  <v-app>
    <div class="d-flex justify-center mt-2">
      <v-date-picker v-model="date" show-adjacent-months></v-date-picker>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    date: null,
  }),
};
</script>

Customizing the Date Picker Width

We can customize the width of the date picker using the width prop:

<template>
  <v-app>
    <div class="d-flex justify-center mt-2">
      <v-date-picker v-model="date" width="400"></v-date-picker>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    date: null,
  }),
};
</script>

Full Width

We can also use the full-width prop to make the date picker take up all the available width of its parent:

Date Picker Event Dates

We can specify events by assigning arrays, objects or functions to the events prop. And we can the event-color prop to change the default color of the mark the date picker uses to indicate the events. Here, we set events to all the odd number days in the month of March 2022 to mark them.

<template>
  <v-app>
    <div class="d-flex justify-center mt-2">
      <v-date-picker
        v-model="date"
        :events="eventDates"
        event-color="green"
      ></v-date-picker>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    date: null,
    eventDates: null,
  }),
  mounted() {
    this.eventDates = [...Array(31)]
      .map((value, index) => index + 1)
      .filter((value) => value % 2 === 0)
      .map((value) => {
        const date = new Date();
        date.setDate(value);
        return date.toISOString().substr(0, 10);
      });
  },
};
</script>

Summary

We use date pickers to allow users select a date or a range of dates. Vuetify provides the v-date-picker component for creating and customizing date pickers.

A switch allows a user to choose between two distinct values.

You can use them in place of a checkbox in your UI.

In this article, we’re going to learn about the Vuetify switch component and the different ways of customizing it.

The v-switch component

v-switch is the name of the component Vuetify provides for creating a switch:

<template>
  <v-app>
    <div class="d-flex justify-center mt-2">
      <v-switch></v-switch>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Clicking the switch turns it on:

Two-way binding with v-model

We can set up a two-way binding between the value of the switch and a variable with v-model. In the code below, we’ve created a switch and a button below it for turning it off. We added a click handler to the button that will set switch1 to false, which will turn the switch off due to the v-model. The two-way binding also ensures that toggling the switch in the user interface will update switch1.

<template>
  <v-app>
    <div class="d-flex justify-center mt-2">
      <v-switch v-model="switch1"></v-switch>
    </div>
    <div class="d-flex justify-center mt-2">
      <v-btn color="primary" @click="switch1 = false">Turn off</v-btn>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    switch1: false,
  }),
};
</script>

Clicking the button turns off the switch:

Switch labels

We can explain the function of a switch to users with the label prop:

<template>
  <v-app>
    <div class="d-flex justify-center mt-2">
      <v-switch
        v-model="switch1"
        :label="`Switch: ${switch1 ? 'on' : 'off'}`"
      ></v-switch>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    switch1: false,
  }),
};
</script>

Custom HTML labels

To include HTML in the label of a switch, use the label slot:

<template>
  <v-app>
    <div class="d-flex justify-center mt-2">
      <v-switch v-model="switch1">
        <template v-slot:label>
          Switch:
          <b :class="{ 'primary--text': switch1 }">{{
            switch1 ? 'on' : 'off'
          }}</b>
        </template>
      </v-switch>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    switch1: false,
  }),
};
</script>

Custom colors

Like many other Vuetify components, v-switch comes with the color prop which allows us to set a custom color:

<template>
  <v-app>
    <div class="d-flex justify-center mt-2">
      <v-col sm="4" class="d-flex justify-center"
        ><v-switch color="red" label="red"></v-switch>
      </v-col>
      <v-col sm="4" class="d-flex justify-center"
        ><v-switch color="primary" label="primary"></v-switch>
      </v-col>
      <v-col sm="4" class="d-flex justify-center"
        ><v-switch color="green" label="green"></v-switch>
      </v-col>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Flat switch

We can use the flat prop to remove the elevation on the thumb of a switch.

<template>
  <v-app>
    <div class="d-flex justify-center mt-2">
      <v-switch
        v-model="switch1"
        :label="`Switch: ${switch1 ? 'on' : 'off'}`"
        flat
      ></v-switch>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    switch1: false,
  }),
};
</script>

Switch in inset mode

To render a switch in inset mode, set the inset prop to true:

<template>
  <v-app>
    <div class="d-flex justify-center mt-2">
      <v-switch
        v-model="switch1"
        :label="`Switch: ${switch1 ? 'on' : 'off'}`"
        inset
      ></v-switch>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    switch1: false,
  }),
};
</script>

Pass array to v-model

We can pass a shared array variable to the v-models of multiple switch components.

<template>
  <v-app>
    <div class="d-flex justify-center mt-2">
      {{ people }}
    </div>

    <div class="d-flex justify-center mt-2">
      <v-switch
        v-model="people"
        color="primary"
        label="Peter"
        value="Peter"
      ></v-switch>
    </div>
    <div class="d-flex justify-center mt-2">
      <v-switch
        v-model="people"
        color="primary"
        label="Daniel"
        value="Daniel"
      ></v-switch>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    people: [],
  }),
};
</script>

Toggling any one of the switches will update the array:

Disabled switch

We can use the disabled prop to disable a switch:

<template>
  <v-app>
    <div class="d-flex justify-center mt-2">
      <v-switch label="off disabled" :value="false" disabled></v-switch>
    </div>
    <div class="d-flex justify-center mt-2">
      <v-switch label="on disabled" :value="true" disabled></v-switch>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Switch in loading state

Use the loading prop to set a switch to the loading state:

<template>
  <v-app>
    <div class="d-flex justify-center mt-2">
      <v-switch label="off loading" :value="false" loading="primary"></v-switch>
    </div>
    <div class="d-flex justify-center mt-2">
      <v-switch label="on loading" :value="true" loading="primary"></v-switch>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Key takeaways

Switches are useful for taking boolean input from users.

Use the v-switch component and its various props to create and customize them.

A radio button is useful when you need to obtain user input from a group of options. For example, a user can select a preferred language or country with it. In this article, we’re going to learn how to create and customize a radio button using Vuetify.

The Vuetify Radio Button Component

Use the v-radio component to create a basic radio button:

<template>
  <v-app>
    <div class="d-flex justify-center mt-4">
      <v-radio></v-radio>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Radio Button Labels

To describe a radio button to the user, we can use the label prop:

<template>
  <v-app>
    <div class="d-flex justify-center mt-4">
      <v-radio label="Radio"></v-radio>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Radio buttons are typically used with radio groups in Vuetify. We can do this by wrapping all the v-radios in a v-radio-group. We can then set up a two-way binding with the radio group component through v-model, which will allow us to access and set the currently selected radio button in the group:

<template>
  <v-app>
    <div class="d-flex justify-center mt-4">
      <v-radio-group v-model="radioGroup">
        <v-radio
          v-for="n in 3"
          :key="n"
          :label="`Radio ${n}`"
          :value="n"
        ></v-radio>
      </v-radio-group>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    radioGroup: 1,
  }),
};
</script>

Clicking on another radio button in the group will update the variable and change the selection:

Radio Button Custom Colors

The radio button component has a color prop that we can use to customize its color:

<template>
  <v-app>
    <div class="d-flex justify-center mt-4">
      <v-radio-group v-model="radioGroup">
        <v-radio
          v-for="(color, i) in colors"
          :key="i"
          :label="color"
          :value="color"
          :color="color"
        ></v-radio>
      </v-radio-group>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    colors: ['indigo', 'yellow', 'error', 'green', 'primary'],
  }),
};
</script>

Radio Button Directions

We can use the row prop to present the radio buttons horizontally:

<template>
  <v-app>
    <div class="d-flex justify-center mt-4">
      <v-radio-group v-model="radioGroup" row>
        <v-radio
          v-for="i in 3"
          :key="i"
          :label="`Option ${i}`"
          :value="i"
        ></v-radio>
      </v-radio-group>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

The column prop will present radio buttons vertically, and is the default direction:

<template>
  <v-app>
    <div class="d-flex justify-center mt-4">
      <v-radio-group v-model="radioGroup" column>
        <v-radio
          v-for="i in 3"
          :key="i"
          :label="`Option ${i}`"
          :value="i"
        ></v-radio>
      </v-radio-group>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Ensuring a Mandatory Value

To make sure a radio group always has a value, set the mandatory prop to true:

<template>
  <v-app>
    <div class="d-flex justify-center mt-4">
      <v-radio-group v-model="radioGroup" mandatory>
        <v-radio
          v-for="i in 3"
          :key="i"
          :label="`Option ${i}`"
          :value="i"
        ></v-radio>
      </v-radio-group>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

Labels with HTML

If we want to include HTML in the label of a radio group, we can put the content in the label slot of the v-radio-group:

<template>
  <v-app>
    <div class="d-flex justify-center mt-4">
      <v-radio-group v-model="radioGroup" mandatory>
        <template v-slot:label> Pick an <strong>option</strong> </template>
        <v-radio
          v-for="i in 3"
          :key="i"
          :label="`Option ${i}`"
          :value="i"
        ></v-radio>
      </v-radio-group>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
};
</script>

We can also include HTML in the labels of the radio buttons with their own label slots:

<template>
  <v-app>
    <div class="d-flex justify-center mt-4">
      <v-radio-group v-model="selected">
        <template v-slot:label>
          Select your default <strong>search engine</strong>
        </template>
        <v-radio v-for="(url, name) in searchEngines" :key="name" :value="name"
          ><template v-slot:label
            ><a :href="url">{{ name }}</a></template
          ></v-radio
        >
      </v-radio-group>
    </div>
  </v-app>
</template>

<script>
export default {
  name: 'App',
  data: () => ({
    selected: 'Google',
    searchEngines: {
      Bing: 'https://bing.com',
      Google: 'https://google.com',
      Duckduckgo: 'https://duckduckgo.com',
    },
  }),
};
</script>

Summary

We can create a group of radio buttons when we want to receive user input from a predefined set of options. Vuetify provides the v-radio component to create radio buttons and the v-radio-group component to add groupable functionality to them. These components come with various props for customization.
