Switch

Switch

A control element that allows for a binary selection.

Anatomy

To set up the switch 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 Switch.Root element of the switch is a label element. This is because the switch 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 Switch.Root component.

Examples

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

import { Switch } from '@ark-ui/react'

export const Basic = () => (
  <Switch.Root>
    <Switch.Control>
      <Switch.Thumb />
    </Switch.Control>
    <Switch.Label>Label</Switch.Label>
    <Switch.HiddenInput />
  </Switch.Root>
)

Controlled Switch

For a controlled Switch component, the state of the toggle is managed using the checked prop, and updates when the onCheckedChange event handler is called:

import { useState } from 'react'
import { Switch } from '@ark-ui/react'

export const Controlled = () => {
  const [checked, setChecked] = useState(false)

  return (
    <Switch.Root checked={checked} onCheckedChange={(e) => setChecked(e.checked)}>
      <Switch.Control>
        <Switch.Thumb />
      </Switch.Control>
      <Switch.Label>Label</Switch.Label>
      <Switch.HiddenInput />
    </Switch.Root>
  )
}

Render Prop Usage

The Switch component also allows for a render prop, granting direct access to its internal state. This enables you to dynamically adjust and customize aspects of the component based on its current state:

import { Switch } from '@ark-ui/react'

export const RenderProp = () => (
  <Switch.Root>
    <Switch.Control>
      <Switch.Thumb />
    </Switch.Control>
    <Switch.Context>
      {(context) => (
        <Switch.Label>Feature is {context.checked ? 'enabled' : 'disabled'}</Switch.Label>
      )}
    </Switch.Context>
    <Switch.HiddenInput />
  </Switch.Root>
)

Using the Field Component

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

import { Field, Switch } from '@ark-ui/react'

export const WithField = (props: Field.RootProps) => (
  <Field.Root {...props}>
    <Switch.Root>
      <Switch.Control>
        <Switch.Thumb />
      </Switch.Control>
      <Switch.Label>Label</Switch.Label>
      <Switch.HiddenInput />
    </Switch.Root>
    <Field.HelperText>Additional Info</Field.HelperText>
    <Field.ErrorText>Error Info</Field.ErrorText>
  </Field.Root>
)
