# ToggleButtonGroup

A toggle button group allows a user to toggle multiple options, with single or multiple selection.

## Selection

Use the `selectionMode` prop to enable single or multiple selection. The selected items can be controlled via the `selectedKeys` prop, matching the `id` of each `<ToggleButton>`. Items can be disabled with the `isDisabled` prop. See the [selection guide](selection.html?component=ToggleButtonGroup) for more details.

```tsx
import type {Key} from 'react-aria-components';
import {useState} from 'react';
import {ToggleButtonGroup} from 'vanilla-starter/ToggleButtonGroup';
import {ToggleButton} from 'vanilla-starter/ToggleButton';
import {Bold, Italic, Underline, Strikethrough} from 'lucide-react';

function Example(props) {
  let [selected, setSelected] = useState(new Set<Key>(['bold']));

  return (
    <>
      <ToggleButtonGroup
        {...props}
        aria-label="Text style"
        /*- begin highlight -*/
        
        selectedKeys={selected}
        onSelectionChange={setSelected}>
        {/*- end highlight -*/}
        <ToggleButton id="bold" aria-label="Bold">
          <Bold size={18} />
        </ToggleButton>
        <ToggleButton id="italic" aria-label="Italic" isDisabled>
          <Italic size={18} />
        </ToggleButton>
        <ToggleButton id="underline" aria-label="Underline">
          <Underline size={18} />
        </ToggleButton>
        <ToggleButton id="strike" aria-label="Strikethrough">
          <Strikethrough size={18} />
        </ToggleButton>
      </ToggleButtonGroup>
      <p>Current selection: {[...selected].join(', ')}</p>
    </>
  );
}
```

### Animation

Render a [SelectionIndicator](selection.html#animated-selectionindicator) within each `ToggleButton` to animate selection changes.

```tsx
import {ToggleButtonGroup, ToggleButton, ToggleButtonProps, SelectionIndicator} from 'react-aria-components';
import 'vanilla-starter/SegmentedControl.css';

function SegmentedControlItem(props: ToggleButtonProps) {
  return (
    <ToggleButton {...props} className="segmented-control-item">
      {/*- begin highlight -*/}
      <SelectionIndicator className="react-aria-SelectionIndicator button-base" data-selected />
      {/*- end highlight -*/}
      <span>{props.children}</span>
    </ToggleButton>
  );
}

<ToggleButtonGroup
  className="segmented-control button-base"
  data-variant="secondary"
  defaultSelectedKeys={['day']}
  disallowEmptySelection>
  <SegmentedControlItem id="day">Day</SegmentedControlItem>
  <SegmentedControlItem id="week">Week</SegmentedControlItem>
  <SegmentedControlItem id="month">Month</SegmentedControlItem>
  <SegmentedControlItem id="year">Year</SegmentedControlItem>
</ToggleButtonGroup>
```

## API

```tsx

```
