Checkbox

A checkbox allows a user to select multiple items from a list of individual items, or to mark one individual item as selected.

Features#

Checkboxes can be built with the <input> HTML element, but this can be difficult to style. Checkbox helps achieve accessible checkboxes that can be styled as needed.

• Styleable – Hover, press, keyboard focus, selection, and indeterminate states are provided for easy styling. These states only apply when interacting with an appropriate input device, unlike CSS pseudo classes.
• Accessible – Uses a visually hidden <input> element under the hood, which also enables HTML form integration and autofill. A label element is built-in to ensure the checkbox is usable with assistive technologies.
• Cross-browser – Mouse, touch, keyboard, and focus interactions are normalized to ensure consistency across browsers and devices.

Anatomy#

A checkbox consists of a visual selection indicator and a label. Checkboxes support three selection states: checked, unchecked, and indeterminate. Users may click or touch a checkbox to toggle the selection state, or use the Tab key to navigate to it and the Space key to toggle it.

In most cases, checkboxes should have a visual label. If the checkbox does not have a visible label, an aria-label or aria-labelledby prop must be passed instead to identify the element to assistive technology.

Props#

Styling#

React Aria components can be styled in many ways, including using CSS classes, inline styles, utility classes (e.g. Tailwind), CSS-in-JS (e.g. Styled Components), etc. By default, all components include a builtin className attribute which can be targeted using CSS selectors. These follow the react-aria-ComponentName naming convention.

.react-aria-Checkbox {
  /* ... */
}

.react-aria-Checkbox {
  /* ... */
}

.react-aria-Checkbox {
  /* ... */
}

A custom className can also be specified on any component. This overrides the default className provided by React Aria with your own.

<Checkbox className="my-checkbox">
  {/* ... */}
</Checkbox>

<Checkbox className="my-checkbox">
  {/* ... */}
</Checkbox>

<Checkbox className="my-checkbox">
  {/* ... */}
</Checkbox>

In addition, some components support multiple UI states (e.g. focused, placeholder, readonly, etc.). React Aria components expose states using DOM attributes, which you can target in CSS selectors. These are ARIA attributes wherever possible, or data attributes when a relevant ARIA attribute does not exist. For example:

.react-aria-Checkbox[data-pressed] {
  /* ... */
}

.react-aria-Checkbox[data-pressed] {
  /* ... */
}

.react-aria-Checkbox[data-pressed] {
  /* ... */
}

The className and style props also accept functions which receive states for styling. This lets you dynamically determine the classes or styles to apply, which is useful when using utility CSS libraries like Tailwind.

<Checkbox
  className={({ isPressed }) => isPressed ? 'bg-gray-700' : 'bg-gray-600'}
/>

<Checkbox
  className={({ isPressed }) =>
    isPressed ? 'bg-gray-700' : 'bg-gray-600'}
/>

<Checkbox
  className={(
    { isPressed }
  ) =>
    isPressed
      ? 'bg-gray-700'
      : 'bg-gray-600'}
/>

Render props may also be used as children to alter what elements are rendered based on the current state. For example, you could render an extra element when the checkbox is selected.

<Checkbox>
  {({isSelected}) => (
    <>
      {isSelected && <CheckIcon />}
      Subscribe
    </>
  )}
</Checkbox>

<Checkbox>
  {({isSelected}) => (
    <>
      {isSelected && <CheckIcon />}
      Subscribe
    </>
  )}
</Checkbox>

<Checkbox>
  {(
    { isSelected }
  ) => (
    <>
      {isSelected && (
        <CheckIcon />
      )}
      Subscribe
    </>
  )}
</Checkbox>

The states, selectors, and render props for Checkbox are documented below.

Reusable wrappers#

If you will use a Checkbox in multiple places in your app, you can wrap all of the pieces into a reusable component. This way, the DOM structure, styling code, and other logic are defined in a single place and reused everywhere to ensure consistency.

This example wraps Checkbox and all of its children together into a single component. It also shows how to use render props to conditionally render a different indicator icon when the checkbox is in an indeterminate state.

import type {CheckboxProps} from 'react-aria-components';

function MyCheckbox({children, ...props}: CheckboxProps) {
  return (
    <Checkbox {...props}>
      {({isIndeterminate}) => <>
        <div className="checkbox">
          <svg viewBox="0 0 18 18" aria-hidden="true">
            {isIndeterminate
              ? <rect x={1} y={7.5} width={15} height={3} />
              : <polyline points="1 9 7 14 15 4" />
            }
          </svg>
        </div>
        {children}
      </>}
    </Checkbox>
  );
}

<MyCheckbox>Unsubscribe</MyCheckbox>

import type {CheckboxProps} from 'react-aria-components';

function MyCheckbox({children, ...props}: CheckboxProps) {
  return (
    <Checkbox {...props}>
      {({isIndeterminate}) => <>
        <div className="checkbox">
          <svg viewBox="0 0 18 18" aria-hidden="true">
            {isIndeterminate
              ? <rect x={1} y={7.5} width={15} height={3} />
              : <polyline points="1 9 7 14 15 4" />
            }
          </svg>
        </div>
        {children}
      </>}
    </Checkbox>
  );
}

<MyCheckbox>Unsubscribe</MyCheckbox>

import type {CheckboxProps} from 'react-aria-components';

function MyCheckbox(
  { children, ...props }:
    CheckboxProps
) {
  return (
    <Checkbox {...props}>
      {(
        {
          isIndeterminate
        }
      ) => (
        <>
          <div className="checkbox">
            <svg
              viewBox="0 0 18 18"
              aria-hidden="true"

              {isIndeterminate
                ? (
                  <rect
                    x={1}
                    y={7.5}
                    width={15}
                    height={3}
                  />
                )
                : (

<MyCheckbox>

</MyCheckbox>

Usage#

The following examples show how to use the MyCheckbox component created in the above example.

Default value#

Checkboxes are not selected by default. The defaultSelected prop can be used to set the default state.

<MyCheckbox defaultSelected>Subscribe</MyCheckbox>

<MyCheckbox defaultSelected>Subscribe</MyCheckbox>

<MyCheckbox
  defaultSelected
>
  Subscribe
</MyCheckbox>

Controlled value#

The isSelected prop can be used to make the selected state controlled. The onChange event is fired when the user presses the checkbox, and receives the new value.

function Example() {
  let [selected, setSelection] = React.useState(false);

  return (
    <>
      <MyCheckbox isSelected={selected} onChange={setSelection}>
        Subscribe
      </MyCheckbox>
      <p>{`You are ${selected ? 'subscribed' : 'unsubscribed'}`}</p>
    </>
  );
}

function Example() {
  let [selected, setSelection] = React.useState(false);

  return (
    <>
      <MyCheckbox
        isSelected={selected}
        onChange={setSelection}
      >
        Subscribe
      </MyCheckbox>
      <p>
        {`You are ${
          selected ? 'subscribed' : 'unsubscribed'
        }`}
      </p>
    </>
  );
}

function Example() {
  let [
    selected,
    setSelection
  ] = React.useState(
    false
  );

  return (
    <>
      <MyCheckbox
        isSelected={selected}
        onChange={setSelection}
      >
        Subscribe
      </MyCheckbox>
      <p>
        {`You are ${
          selected
            ? 'subscribed'
            : 'unsubscribed'
        }`}
      </p>
    </>
  );
}

Indeterminate#

A Checkbox can be in an indeterminate state, controlled using the isIndeterminate prop. This overrides the appearance of the Checkbox, whether selection is controlled or uncontrolled. The Checkbox will visually remain indeterminate until the isIndeterminate prop is set to false, regardless of user interaction.

<MyCheckbox isIndeterminate>Subscribe</MyCheckbox>

<MyCheckbox isIndeterminate>Subscribe</MyCheckbox>

<MyCheckbox
  isIndeterminate
>
  Subscribe
</MyCheckbox>

Validation#

Checkboxes can display a validation state to communicate to the user if the current value is invalid. Implement your own validation logic in your app and pass "invalid" to the Checkbox via the validationState prop.

<MyCheckbox validationState="invalid">
  I accept the terms and conditions
</MyCheckbox>

<MyCheckbox validationState="invalid">
  I accept the terms and conditions
</MyCheckbox>

<MyCheckbox validationState="invalid">
  I accept the terms
  and conditions
</MyCheckbox>

Disabled#

Checkboxes can be disabled using the isDisabled prop.

<MyCheckbox isDisabled>Subscribe</MyCheckbox>

<MyCheckbox isDisabled>Subscribe</MyCheckbox>

<MyCheckbox isDisabled>
  Subscribe
</MyCheckbox>

Read only#

The isReadOnly prop makes the selection immutable. Unlike isDisabled, the Checkbox remains focusable. See the MDN docs for more information.

<MyCheckbox isSelected isReadOnly>Agree</MyCheckbox>

<MyCheckbox isSelected isReadOnly>Agree</MyCheckbox>

<MyCheckbox
  isSelected
  isReadOnly
>
  Agree
</MyCheckbox>

HTML forms#

Checkbox supports the name and value props for integration with HTML forms.

<MyCheckbox name="newsletter" value="subscribe">Subscribe</MyCheckbox>

<MyCheckbox name="newsletter" value="subscribe">
  Subscribe
</MyCheckbox>

<MyCheckbox
  name="newsletter"
  value="subscribe"
>
  Subscribe
</MyCheckbox>

Advanced customization#

Hooks#

If you need to customize things further, such as accessing internal state or customizing DOM structure, you can drop down to the lower level Hook-based API. See useCheckbox for more details.
