An input element to toggle between checked and unchecked states.

Usage

Use the v-model directive to control the checked state of the Checkbox.

<script setup lang="ts">
const value = ref(true)
</script>

<template>
  <UCheckbox v-model="value" />
</template>

Use the default-value prop to set the initial value when you do not need to control its state.

<template>
  <UCheckbox default-value />
</template>

Indeterminate

Use the indeterminate prop to set the Checkbox to an indeterminate state.

<template>
  <UCheckbox indeterminate />
</template>

Indeterminate Icon

Use the indeterminate-icon prop to customize the indeterminate icon. Defaults to i-lucide-minus.

<template>
  <UCheckbox indeterminate indeterminate-icon="i-lucide-plus" />
</template>
You can customize this icon globally in your app.config.ts under ui.icons.minus key.

Label

Use the label prop to set the label of the Checkbox.

<template>
  <UCheckbox label="Check me" />
</template>

When using the required prop, an asterisk is added next to the label.

<template>
  <UCheckbox required label="Check me" />
</template>

Description

Use the description prop to set the description of the Checkbox.

This is a checkbox.

<template>
  <UCheckbox label="Check me" description="This is a checkbox." />
</template>

Icon

Use the icon prop to set the icon of the Checkbox when it is checked. Defaults to i-lucide-check.

<template>
  <UCheckbox icon="i-lucide-heart" default-value label="Check me" />
</template>
You can customize this icon globally in your app.config.ts under ui.icons.check key.

Color

Use the color prop to change the color of the Checkbox.

<template>
  <UCheckbox color="neutral" default-value label="Check me" />
</template>

Size

Use the size prop to change the size of the Checkbox.

<template>
  <UCheckbox size="xl" default-value label="Check me" />
