}

.Button {
  box-sizing: border-box;
  display: flex;
  align-items: center;
  justify-content: center;
  width: 2rem;
  height: 2rem;
  padding: 0;

  border: none;
  border-radius: 0;
  background-color: transparent;
  color: oklch(14.5% 0 0deg);

## Anatomy

Import the component and use it as a single part:

```jsx title="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.
