Checkbox

Checkbox

A control element that allows for multiple selections within a set.

Anatomy

To set up the checkbox correctly, you'll need to understand its anatomy and how we name its parts.

Each part includes a data-part attribute to help identify them in the DOM.

Design impact on the asChild property

The Checkbox.Root element of the checkbox is a label element. This is because the checkbox is a form control and should be associated with a label to provide context and meaning to the user. Otherwise, the HTML and accessibility structure will be invalid.

If you need to use the asChild property, make sure that the label element is the direct child of the Checkbox.Root component.

Examples

Learn how to use the Checkbox component in your project. Let's take a look at the most basic example:

import { CheckIcon } from 'lucide-solid'
import { Checkbox } from '@ark-ui/solid'

export const Basic = () => (
  <Checkbox.Root>
    <Checkbox.Label>Checkbox</Checkbox.Label>
    <Checkbox.Control>
      <Checkbox.Indicator>
        <CheckIcon />
      </Checkbox.Indicator>
    </Checkbox.Control>
    <Checkbox.HiddenInput />
  </Checkbox.Root>
)

Controlled Checkbox

To create a controlled Checkbox component, manage the state of the checked status using the checked prop and update it when the onCheckedChange event handler is called:

import { CheckIcon } from 'lucide-solid'
import { createSignal } from 'solid-js'
import { Checkbox } from '@ark-ui/solid'

export const Controlled = () => {
  const [checked, setChecked] = createSignal<Checkbox.CheckedState>(true)
  return (
    <Checkbox.Root checked={checked()} onCheckedChange={(e) => setChecked(e.checked)}>
      <Checkbox.Label>Checkbox</Checkbox.Label>
      <Checkbox.Control>
        <Checkbox.Indicator>
          <CheckIcon />
        </Checkbox.Indicator>
      </Checkbox.Control>
      <Checkbox.HiddenInput />
    </Checkbox.Root>
  )
}

Indeterminate Checkbox

In some cases, you may need a checkbox to represent a state that is neither checked nor unchecked, known as the indeterminate state. This can be achieved by setting the checked prop to indeterminate:

import { CheckIcon, MinusIcon } from 'lucide-solid'
import { Checkbox } from '@ark-ui/solid'

export const Indeterminate = () => (
  <Checkbox.Root checked="indeterminate">
    <Checkbox.Label>Checkbox</Checkbox.Label>
    <Checkbox.Control>
      <Checkbox.Indicator>
        <CheckIcon />
      </Checkbox.Indicator>
      <Checkbox.Indicator indeterminate>
        <MinusIcon />
      </Checkbox.Indicator>
    </Checkbox.Control>
    <Checkbox.HiddenInput />
  </Checkbox.Root>
)

Checkbox Group

Ark provides a Checkbox.Group component to manage a group of checkboxes. The Checkbox.Group component manages the state of the checkboxes and provides a way to access the checked values:

import { CheckIcon } from 'lucide-solid'
import { For } from 'solid-js'
import { Checkbox, CheckboxGroup } from '@ark-ui/solid'

const items = [
  { label: 'React', value: 'react' },
  { label: 'Solid', value: 'solid' },
  { label: 'Vue', value: 'vue' },
]

export const Group = () => (
  <CheckboxGroup defaultValue={['react']} onValueChange={console.log}>
    <For each={items}>
      {(item) => (
        <Checkbox.Root value={item.value}>
          <Checkbox.Label>{item.label}</Checkbox.Label>
          <Checkbox.Control>
            <Checkbox.Indicator>
              <CheckIcon />
            </Checkbox.Indicator>
          </Checkbox.Control>
          <Checkbox.HiddenInput />
        </Checkbox.Root>
      )}
    </For>
  </CheckboxGroup>
)

Render Prop Usage

For cases where you need more flexibility in rendering, the Checkbox component offers the use of a render prop. The render prop function gives you access to the checkbox's API, allowing you to customize the checkbox control's rendering:

import { CheckIcon } from 'lucide-solid'
import { Checkbox } from '@ark-ui/solid'

export const RenderProp = () => (
  <Checkbox.Root>
    <Checkbox.Control>
      <Checkbox.Indicator>
        <CheckIcon />
      </Checkbox.Indicator>
    </Checkbox.Control>
    <Checkbox.Context>
      {(checkbox) => <Checkbox.Label>Checkbox {checkbox().checked.toString()}</Checkbox.Label>}
    </Checkbox.Context>
    <Checkbox.HiddenInput />
  </Checkbox.Root>
)

Using the Field Component

The Field component helps manage form-related state and accessibility attributes of a checkbox. It includes handling ARIA labels, helper text, and error text to ensure proper accessibility.

import { CheckIcon, MinusIcon } from 'lucide-solid'
import { Checkbox, Field } from '@ark-ui/solid'

export const WithField = (props: Field.RootProps) => (
  <Field.Root {...props}>
    <Checkbox.Root>
      <Checkbox.Label>Label</Checkbox.Label>
      <Checkbox.Control>
        <Checkbox.Indicator>
          <CheckIcon />
        </Checkbox.Indicator>
        <Checkbox.Indicator indeterminate>
          <MinusIcon />
        </Checkbox.Indicator>
      </Checkbox.Control>
      <Checkbox.HiddenInput />
    </Checkbox.Root>
    <Field.HelperText>Additional Info</Field.HelperText>
    <Field.ErrorText>Error Info</Field.ErrorText>
  </Field.Root>
)
