How to Use the Vuetify Checkbox Component
A checkbox allows a user to select between two values. They are useful for getting boolean input (true or false), perhaps checking off a task in a to-do list app to show completion or deciding whether or not to accept a license agreement during software installation. In this article, we’re going to learn how to create a checkbox in Vuetify.
The v-checkbox Component
Vuetify provides the v-checkbox component for creating a checkbox:
<template>
<v-app>
<v-row class="ma-2" justify="center">
<v-checkbox></v-checkbox>
</v-row>
</v-app>
</template>
<script>
export default {
name: 'App',
};
</script>
Clicking the checkbox will toggle its checked state:
Setting a Checkbox value
Use the value prop to set the checked state of the checkbox.
<template>
<v-app>
<v-row class="ma-2" justify="center">
<v-checkbox :value="true"></v-checkbox>
<v-checkbox :value="false"></v-checkbox>
</v-row>
</v-app>
</template>
<script>
export default {
name: 'App',
};
</script>
Vuetify Checkbox Labels
We can label a Vuetify checkbox with the label prop:
<template>
<v-app>
<v-row class="ma-2" justify="center">
<v-checkbox v-model="checked" label="Coding Beauty"></v-checkbox>
</v-row>
</v-app>
</template>
<script>
export default {
name: 'App',
data: () => ({
checked: false,
}),
};
</script>
Vuetify Checkbox Label Slot
To include HTML content in a checkbox label, we can put it in the label slot:
<template>
<v-app>
<v-row class="ma-2" justify="space-around">
<v-checkbox color="indigo" input-value="true">
<template v-slot:label>
Visit the
<a
target="_blank"
href="https://codingbeautydev.com"
@click.stop
v-on="on"
>
Coding Beauty website
</a>
</template>
</v-checkbox>
</v-row>
</v-app>
</template>
<script>
export default {
name: 'App',
};
</script>
Vuetify Checkbox Boolean v-model
To control the current value of the checkbox, we can use v-model to create a two-way binding between the v-checkbox and a boolean variable.
Here, we create a checkbox and a button below it to toggle the state of the checkbox. We indicate this state with some text in the label prop.
<template>
<v-app>
<div class="ma-2 d-flex justify-center">
<v-checkbox v-model="checked" :label="`Checked: ${checked}`"></v-checkbox>
</div>
<div class="ma-2 d-flex justify-center">
<v-btn color="indigo" dark @click="checked = !checked">{{
checked ? 'Uncheck' : 'Check'
}}</v-btn>
</div>
</v-app>
</template>
<script>
export default {
name: 'App',
data: () => ({
checked: false,
}),
};
</script>
Clicking the button will negate checked, and this will reflect on the checkbox and its label:
Vuetify Checkbox Array v-model
We can pass an array to v-model to allow multiple checkbox components to share the same variable used for the two-way binding:
<template>
<v-app>
<v-container fluid>
<p>Selected: {{ selected }}</p>
<v-checkbox
v-model="selected"
label="JavaScript"
value="javascript"
></v-checkbox>
<v-checkbox
v-model="selected"
label="TypeScript"
value="typescript"
></v-checkbox>
</v-container>
</v-app>
</template>
<script>
export default {
name: 'App',
data: () => ({
selected: [],
}),
};
</script>
Customizing Checkbox Color in Vuetify
The color prop allows us to set the color of the checkbox background when checked:
<template>
<v-app>
<v-row justify="space-around" class="ma-4">
<v-checkbox color="primary" label="primary"></v-checkbox>
<v-checkbox color="green" label="green"></v-checkbox>
<v-checkbox color="yellow darken-3" label="yellow darken-3"></v-checkbox>
<v-checkbox color="red" label="red"></v-checkbox>
</v-row>
</v-app>
</template>
<script>
export default {
name: 'App',
};
</script>
Disabled Checkbox
We can turn off checkbox interactivity with the disabled prop. It will no longer accept input when disabled.
<template>
<v-app>
<v-row class="ma-2" justify="space-around">
<v-checkbox
label="on disabled"
color="green"
input-value="true"
disabled
></v-checkbox>
<v-checkbox
label="off disabled"
color="green"
disabled
></v-checkbox>
</v-row>
</v-app>
</template>
<script>
export default {
name: 'App',
};
</script>
Indeterminate Checkbox
We can make the checkbox indeterminate by using the indeterminate prop on the v-checkbox:
<template>
<v-app>
<v-row class="ma-2" justify="space-around">
<v-checkbox label="indeterminate" color="red" indeterminate></v-checkbox>
</v-row>
</v-app>
</template>
<script>
export default {
name: 'App',
};
</script>
Summary
We can use a checkbox when we need to accept boolean input. Vuetify provides the v-checkbox component to create it and provides various props for customization.
