/**
 * The `<Dropdown.Menu>` API
 *
 * @description
 * Note the difference between this component and `<Menu>` component:
 * `<Menu>` is used for ARIA menu control logic and is used internally only.
 * This component is only used for supporting submenu syntax and is
 * assigned to Dropdown.Menu
 *
 * @example
 *
 * <Dropdown>
 *   <Dropdown.Item>Item 1</Dropdown.Item>
 *   <Dropdown.Menu title="Submenu">
 *     <Dropdown.Item>Sub item</Dropdown.Item>
 *   </Dropdown.Menu>
 * </Dropdown>
