Single selection

In single selection mode it is important to apply an aria-label to the ActionMenu.Button child. This provides the user with important and durable context on the selection they need to make.

const App = () => {
  const [selection, setSelection] = React.useState('Copilot')

  return (
    <ActionMenu
      onSelect={(newValue) => setSelection(newValue)}
      selectionVariant="single"
    >
      <ActionMenu.Button aria-label="Select a GitHub feature">
        {selection}
      </ActionMenu.Button>
      <ActionMenu.Overlay>
        <ActionMenu.Item value="Copilot" selected={'Copilot' === selection}>
          Copilot
        </ActionMenu.Item>
        <ActionMenu.Item
          value="Codespaces"
          selected={'Codespaces' === selection}
        >
          Codespaces
        </ActionMenu.Item>
        <ActionMenu.Item value="CodeQL" selected={'CodeQL' === selection}>
          CodeQL
        </ActionMenu.Item>
      </ActionMenu.Overlay>
    </ActionMenu>
  )
}

render(<App />)

const App = () => {
  const [selection, setSelection] = React.useState('Copilot')

  return (
    <ActionMenu
      onSelect={(newValue) => setSelection(newValue)}
      selectionVariant="single"
    >
      <ActionMenu.Button aria-label="Select a GitHub feature">
        {selection}
      </ActionMenu.Button>
      <ActionMenu.Overlay>
        <ActionMenu.Item value="Copilot" selected={'Copilot' === selection}>
          Copilot
        </ActionMenu.Item>
        <ActionMenu.Item
          value="Codespaces"
          selected={'Codespaces' === selection}
        >
          Codespaces
        </ActionMenu.Item>
        <ActionMenu.Item value="CodeQL" selected={'CodeQL' === selection}>
          CodeQL
        </ActionMenu.Item>
      </ActionMenu.Overlay>
    </ActionMenu>
  )
}
