Usage guidelines

Form controls must have an accessible name: It can be created using native label elements, the Label component, or the Field and Fieldset components. See Labeling a checkbox group and the forms guide.

Anatomy

Checkbox Group is composed together with Checkbox. Import the components and place them together:

Anatomy

import { Checkbox } from '@base-ui/react/checkbox';
import { CheckboxGroup } from '@base-ui/react/checkbox-group';

<CheckboxGroup>
  <Checkbox.Root />
</CheckboxGroup>

Examples

Labeling a checkbox group

A visible label for the group is created by specifying aria-labelledby on <CheckboxGroup> to reference the id of a sibling element that contains the group label text.

Using aria-labelledby to label a checkbox group

<div id="protocols-label">Allowed network protocols</div>
<CheckboxGroup aria-labelledby="protocols-label">{/* ... */}</CheckboxGroup>

For individual checkboxes, use the Label component. It supports the same enclosing labeling pattern as a native label element, so clicking on any gaps between the label text and checkbox still toggles it.

Using Label to label a checkbox

<Label>
  <Checkbox.Root value="http" />
  HTTP
</Label>

The Field and Fieldset components are alternatives that add validation and group labeling support.

Group label: Since the group contains multiple controls, it can be labeled as a fieldset. Use Fieldset by replacing the <Fieldset.Root> element with <CheckboxGroup> via the render prop. <Fieldset.Legend> provides the visible label for the group.
Individual label: Place each individual checkbox in <Field.Item>, then label it using an enclosing <Field.Label>. Enclosing labels ensure that clicking on any gaps between the label and checkbox still toggles it.

Using Field and Fieldset to label a checkbox group

<Field.Root>
  <Fieldset.Root render={<CheckboxGroup />}>
    <Fieldset.Legend>Allowed network protocols</Fieldset.Legend>
    <Field.Item>
      <Field.Label>
        <Checkbox.Root value="http" />
        HTTP
      </Field.Label>
    </Field.Item>
    <Field.Item>
      <Field.Label>
        <Checkbox.Root value="https" />
        HTTPS
      </Field.Label>
    </Field.Item>
    <Field.Item>
      <Field.Label>
        <Checkbox.Root value="ssh" />
        SSH
      </Field.Label>
    </Field.Item>
  </Fieldset.Root>
</Field.Root>

Form integration

To use a checkbox group in a form, pass the checkbox group’s name to <Field.Root>:

Using Checkbox Group in a form

<Form>
  <Field.Root name="allowedNetworkProtocols">
    <Fieldset.Root render={<CheckboxGroup />}>
      <Fieldset.Legend>Allowed network protocols</Fieldset.Legend>
      <Field.Item>
        <Field.Label>
          <Checkbox.Root value="http" />
          HTTP
        </Field.Label>
      </Field.Item>
      <Field.Item>
        <Field.Label>
          <Checkbox.Root value="https" />
          HTTPS
        </Field.Label>
      </Field.Item>
      <Field.Item>
        <Field.Label>
          <Checkbox.Root value="ssh" />
          SSH
        </Field.Label>
      </Field.Item>
    </Fieldset.Root>
  </Field.Root>
</Form>

Parent checkbox

A checkbox that controls other checkboxes within a <CheckboxGroup> can be created:

Make <CheckboxGroup> a controlled component
Pass an array of all the child checkbox values to the allValues prop on the <CheckboxGroup> component
Add the parent boolean prop to the parent <Checkbox.Root>
