 * @description
 * Represents an individual selectable item within an eui-dropdown menu.
 * Implements keyboard navigation and focus management through the CDK Highlightable interface.
 * Supports nested submenus and active/focused visual states for accessibility.
 * Typically used as a child element within eui-dropdown to create menu options.
 *
 * @usageNotes
 * ### Basic menu item
 * ```html
 * <eui-dropdown>
 *   <button euiButton>Menu</button>
 *   <eui-dropdown-item>Edit</eui-dropdown-item>
 *   <eui-dropdown-item [isActive]="true">Delete</eui-dropdown-item>
 * </eui-dropdown>
 * ```
 *
 * ### Accessibility
 * - Implements menuitem role for proper screen reader announcement
 * - Supports roving tabindex for keyboard navigation
 * - Focus state is visually indicated and programmatically managed
 *
 * ### Notes
 * - Use `isActive` to highlight the currently selected item
 * - Nest `eui-dropdown` inside item via `subDropdown` for hierarchical menus
 * - Focus management is handled automatically by parent dropdown

 * @description
 * A flexible dropdown menu component that displays contextual content in an overlay panel.
 * Supports keyboard navigation, nested submenus, positioning strategies, and accessibility features.
 * Composed of a trigger element that opens a panel containing menu items or custom content.
 * Handles focus management, scroll behavior, and click-outside detection automatically.
 *
 * @usageNotes
 * ### Basic dropdown with menu items
 * ```html
 * <eui-dropdown>
 *   <button euiButton>Open Menu</button>
 *   <eui-dropdown-item>Action 1</eui-dropdown-item>
 *   <eui-dropdown-item>Action 2</eui-dropdown-item>
 * </eui-dropdown>
 * ```
 *
 * ### Accessibility
 * - Implements ARIA menu pattern with proper roles and keyboard navigation
 * - Arrow keys navigate between items, Enter/Space activates selection
 * - Escape closes the dropdown and returns focus to trigger
 * - Screen readers announce menu state changes via aria-expanded
 *
 * ### Notes
 * - Use `position` to control dropdown placement (top, right, bottom, left)
 * - Enable `isExpandOnHover` for submenu expansion without clicking
 * - Set `hasClosedOnClickInside` to false for multi-select scenarios
 * - Context menus can be triggered with right-click using `isRightClickEnabled`
