Checkbox

People need to be able to accept the terms and conditions they don't read somehow.

Discoverability

Decide where your events can be found across the web.

Make this event visible on your profile.

Allow others to embed your event details on their own site.

import { Checkbox, CheckboxField, CheckboxGroup } from '@/components/checkbox'
import { Description, Fieldset, Label, Legend } from '@/components/fieldset'
import { Text } from '@/components/text'

function Example() {
  return (
    <Fieldset>
      <Legend>Discoverability</Legend>
      <Text>Decide where your events can be found across the web.</Text>
      <CheckboxGroup>
        <CheckboxField>
          <Checkbox name="discoverability" value="show_on_events_page" defaultChecked />
          <Label>Show on events page</Label>
          <Description>Make this event visible on your profile.</Description>
        </CheckboxField>
        <CheckboxField>
          <Checkbox name="discoverability" value="allow_embedding" />
          <Label>Allow embedding</Label>
          <Description>Allow others to embed your event details on their own site.</Description>
        </CheckboxField>
      </CheckboxGroup>
    </Fieldset>
  )
}

Examples

Basic example

Use the Checkbox component on its own to render a standalone checkbox without an associated Label component:

import { Checkbox } from '@/components/checkbox'

function Example() {
  return <Checkbox aria-label="Allow embedding" name="allow_embedding" />
}

Make sure to provide an aria-label for assistive technology, or connect the Checkbox to your own <label> element using an id.

With label

Wrap a Label and Checkbox with the CheckboxField component to automatically associate them using a generated ID:

import { Checkbox, CheckboxField } from '@/components/checkbox'
import { Label } from '@/components/fieldset'

function Example() {
  return (
    <CheckboxField>
      <Checkbox name="allow_embedding" />
      <Label>Allow embedding</Label>
    </CheckboxField>
  )
}

With description

Use the CheckboxField, Label, and Description components to add a description below the checkbox:

Allow others to embed your event details on their own site.

import { Checkbox, CheckboxField } from '@/components/checkbox'
import { Description, Label } from '@/components/fieldset'

function Example() {
  return (
    <CheckboxField>
      <Checkbox name="allow_embedding" />
      <Label>Allow embedding</Label>
      <Description>Allow others to embed your event details on their own site.</Description>
    </CheckboxField>
  )
}

With custom layout

Use the unstyled Field component from @headlessui/react directly instead of the styled CheckboxField component to implement a custom layout:

import { Checkbox } from '@/components/checkbox'
import { Label } from '@/components/fieldset'
import { Field as HeadlessField } from '@headlessui/react'

function Example() {
  return (
    <HeadlessField className="flex items-center justify-between gap-4">
      <Label>Allow embedding</Label>
      <Checkbox name="allow_embedding" />
    </HeadlessField>
  )
}

Using the unstyled Field component will ensure important accessibility features are still handled for you like generating IDs and associating elements using aria-* attributes.

With accent color

Use the color prop to choose a different accent color for a checkbox:

import { Checkbox } from '@/components/checkbox'

function Example() {
  return <Checkbox color="sky" defaultChecked />
}

For a full list of included color variants, check out the checkbox color reference.

With custom value

Use the value prop to specify a custom value to use when submitting a form:

import { Checkbox } from '@/components/checkbox'

function Example() {
  return <Checkbox name="embed" value="allow" />
}

Default checked state

Use the defaultChecked prop to set the default state when using the Checkbox as an uncontrolled component:

import { Checkbox } from '@/components/checkbox'

function Example() {
  return <Checkbox defaultChecked />
}

Indeterminate state

Use the indeterminate prop to indicate that the Checkbox is in an indeterminate state, neither toggled on nor off:

import { Checkbox, CheckboxField, CheckboxGroup } from '@/components/checkbox'
import { Label } from '@/components/fieldset'
import { useState } from 'react'

const options = ['Show on events page', 'Allow embedding']

function Example() {
  let [selected, setSelected] = useState(['Show on events page'])

  return (
    <CheckboxGroup role="group" aria-label="Discoverability">
      <CheckboxField>
        <Checkbox
          checked={selected.length > 0}
          indeterminate={selected.length !== options.length}
          onChange={(checked) => setSelected(checked ? options : [])}
        />
        <Label>Select all</Label>
      </CheckboxField>

      {options.map((option) => (
        <CheckboxField key={option}>
          <Checkbox
            name={option}
            checked={selected.includes(option)}
            onChange={(checked) => {
              return setSelected((pending) => {
                return checked ? [...pending, option] : pending.filter((item) => item !== option)
              })
            }}
          />
          <Label>{option}</Label>
        </CheckboxField>
      ))}
    </CheckboxGroup>
  )
}

Controlled component

Use the checked and onChange props to use a Checkbox as a controlled component:

import { Checkbox } from '@/components/checkbox'
import { useState } from 'react'

function Example() {
  let [checked, setChecked] = useState(true)

  return <Checkbox checked={checked} onChange={setChecked} />
}

Multiple checkboxes

Use the CheckboxGroup component to stack multiple checkboxes together in a list:

Make this event visible on your profile.

Allow others to embed your event details on their own site.

import { Checkbox, CheckboxField, CheckboxGroup } from '@/components/checkbox'
import { Description, Label } from '@/components/fieldset'

function Example() {
  return (
    <CheckboxGroup>
      <CheckboxField>
        <Checkbox name="show_on_events_page" defaultChecked />
        <Label>Show on events page</Label>
        <Description>Make this event visible on your profile.</Description>
      </CheckboxField>
      <CheckboxField>
        <Checkbox name="allow_embedding" />
        <Label>Allow embedding</Label>
        <Description>Allow others to embed your event details on their own site.</Description>
      </CheckboxField>
    </CheckboxGroup>
  )
}

You can optionally add role="group" and an aria-label to the CheckboxGroup if all of the checkboxes are related and you want them announced to assistive technology as a group.

With fieldset

Use the Fieldset, Legend, and Text components to add a title and description to a group of checkboxes:

Discoverability

Decide where your events can be found across the web.

Make this event visible on your profile.

Allow others to embed your event details on their own site.

import { Checkbox, CheckboxField, CheckboxGroup } from '@/components/checkbox'
import { Description, Fieldset, Label, Legend } from '@/components/fieldset'
import { Text } from '@/components/text'

function Example() {
  return (
    <Fieldset>
      <Legend>Discoverability</Legend>
      <Text>Decide where your events can be found across the web.</Text>
      <CheckboxGroup>
        <CheckboxField>
          <Checkbox name="discoverability" value="show_on_events_page" defaultChecked />
          <Label>Show on events page</Label>
          <Description>Make this event visible on your profile.</Description>
        </CheckboxField>
        <CheckboxField>
          <Checkbox name="discoverability" value="allow_embedding" />
          <Label>Allow embedding</Label>
          <Description>Allow others to embed your event details on their own site.</Description>
        </CheckboxField>
      </CheckboxGroup>
    </Fieldset>
  )
}

Disabled state

Add the disabled prop to a Checkbox or CheckboxField component to disable it:

Discoverability

Decide where your events can be found across the web.

Make this event visible on your profile.

Allow others to embed your event details on their own site.

import { Checkbox, CheckboxField, CheckboxGroup } from '@/components/checkbox'
import { Description, Fieldset, Label, Legend } from '@/components/fieldset'
import { Text } from '@/components/text'

function Example() {
  return (
    <Fieldset>
      <Legend>Discoverability</Legend>
      <Text>Decide where your events can be found across the web.</Text>
      <CheckboxGroup>
        <CheckboxField>
          <Checkbox name="discoverability" value="show_on_events_page" />
          <Label>Show on events page</Label>
          <Description>Make this event visible on your profile.</Description>
        </CheckboxField>
        <CheckboxField disabled>
          <Checkbox name="discoverability" value="allow_embedding" />
          <Label>Allow embedding</Label>
          <Description>Allow others to embed your event details on their own site.</Description>
        </CheckboxField>
      </CheckboxGroup>
    </Fieldset>
  )
}

You can also add the disabled prop to a Fieldset to disable the entire fieldset.
