Passing Tailwind CSS classes

function CustomToggleButtonGroup() {
  return (
    <ToggleButtonGroup className="bg-purple-100" selectionMode="single">
      <ToggleButton id="a">Option A</ToggleButton>
      <ToggleButton id="b">
        <ToggleButtonGroup.Separator />
        Option B
      </ToggleButton>
    </ToggleButtonGroup>
  );
}

Customizing the component classes

To customize the ToggleButtonGroup component classes, you can use the @layer components directive.

Learn more.

@layer components {
  .toggle-button-group {
    @apply rounded-lg;
  }

  .toggle-button-group__separator {
    @apply opacity-25;
  }

  .toggle-button-group--full-width {
    @apply w-full;
  }
}

Namespace UIKit follows the BEM methodology to ensure component variants and states are reusable and easy to customize.

Notes

ToggleButtonGroup uses React Context to pass size to all child ToggleButton components
Each ToggleButton must have a unique id prop that corresponds to the keys used in selectedKeys / defaultSelectedKeys
The isDisabled prop is handled natively by React Aria and disables all child ToggleButtons — individual buttons can override this by setting isDisabled={false}
The component automatically handles border radius between buttons
Add <ToggleButtonGroup.Separator /> inside each ToggleButton (except the first) to show dividers between buttons
Use disallowEmptySelection with selectionMode="single" to ensure one option is always selected
