The Stencil example uses fs-toggle-group with fs-toggle children. The group owns selection, disabled inheritance, and keyboard focus; no example-specific controller is needed. Use array properties for value / defaultValue, or JSON arrays in HTML attributes such as default-value='["left"]'. The cancelable valueChange event exposes the requested array as event.detail.value; a controlled consumer writes that array back to value.

The Stencil container uses Shadow DOM and exposes ::part(group); each Toggle exposes ::part(control). The Base UI theme is built in; set data-fs-theme="base-ui" on an ancestor to apply the optional theme without component classes. Override the existing --fs-toggle-group-* variables or use the public parts for custom styles.

React’s render API is not a Web Component property; use slotted content and public events. Inside fs-toolbar-root, the migrated toolbar supplies outer composite navigation and disabled inheritance; the group does not create a second tab stop or trap arrow navigation. A Stencil group still does not consume React Toolbar context; compose the Stencil toolbar parts together.

Anatomy

Import the component and use it as a single part:

Anatomy

import { ToggleGroup } from '@base-ui/react/toggle-group';

<ToggleGroup />

Examples

Multiple

Add the multiple prop to allow pressing more than one toggle at a time.
