Check out storybook for live examples.

useButtonGroup

The useButtonGroup hook manages focus, selection and accessibility attributes required for a group of buttons. Garden uses this in react-components for the buttons package.

import { useButtonGroup } from '@zendeskgarden/container-buttongroup';

const ButtonGroup = () => {
  const [controlledSelectedItem, setSelectedItem] = useState();
  const { selectedItem, focusedItem, getButtonProps, getGroupProps } = useButtonGroup({
    selectedItem: controlledSelectedItem,
    onSelect: newSelectedItem => setSelectedItem(newSelectedItem)
  });

  return (
    <div {...getGroupProps()}>
      {buttons.map((button, index) => (
        <button
          {...getButtonProps({
            key: button,
            item: button,
            focusRef: buttonRefs[index],
            ref: buttonRefs[index],
            style: {
              boxShadow: button === focusedItem && 'inset 0 0 0 3px rgba(31,115,183, 0.35)',
              outline: 'none',
              color: button === selectedItem ? '#fff' : '#1f73b7',
              background: button === selectedItem && '#144a75',
              padding: '10px'
            }
          })}
        >
          {button}
        </button>
      ))}
    </div>
  );
};

ExampleContainer

ButtonGroupContainer is a render-prop wrapper for the useButtonGroup hook.

import { ButtonGroupContainer } from '@zendeskgarden/container-buttongroup';

<ButtonGroupContainer>
  {({ selectedItem, focusedItem, getButtonProps, getGroupProps }) => (
    <div {...getGroupProps()}>
      {buttons.map((button, index) => (
        <button
          {...getButtonProps({
            key: button,
            item: button,
            focusRef: buttonRefs[index],
            ref: buttonRefs[index],
            style: {
              boxShadow: button === focusedItem && 'inset 0 0 0 3px rgba(31,115,183, 0.35)',
              outline: 'none',
              color: button === selectedItem ? '#fff' : '#1f73b7',
              background: button === selectedItem && '#144a75',
              padding: '10px'
            }
          })}
        >
          {button}
        </button>
      ))}
    </div>
  )}
</ButtonGroupContainer>;
