/**
 * Represents a single item within an eUI menu structure. Supports hierarchical navigation with expandable/collapsible children,
 * multiple interaction modes (URL navigation, router links, commands, labels), and visual states (collapsed, disabled, selected).
 * Implements keyboard navigation and accessibility features for menu interactions.
 *
 * @usageNotes
 * ### Basic Usage
 * ```typescript
 * // Typically used within EuiMenuComponent via items array
 * item: EuiMenuItem = {
 *   id: 'home',
 *   label: 'Home',
 *   icon: 'eui-home',
 *   url: '/home'
 * };
 * ```
 *
 * ### With Children
 * ```typescript
 * item: EuiMenuItem = {
 *   id: 'settings',
 *   label: 'Settings',
 *   expanded: true,
 *   children: [
 *     { id: 'profile', label: 'Profile', url: '/settings/profile' }
 *   ]
 * };
 * ```
 *
 * ### Accessibility
 * - Implements FocusableOption for keyboard navigation
 * - ARIA attributes for menu item role and state
 * - Keyboard support for Enter, Space, and Arrow keys
 * - Focus management for nested menu structures
 *
 * ### Notes
 * - Automatically managed by parent EuiMenuComponent
 * - Supports tooltips in collapsed menu mode
 * - Can display badges, action icons, and external link indicators

/**
 * Navigation menu component supporting hierarchical item structures with expand/collapse functionality,

 * with optional icons, tooltips, and scroll-to-active-item behavior. Commonly used for application
 * sidebars, navigation panels, and hierarchical content navigation.
 *
 * @usageNotes
 * ### Basic Usage
 * ```typescript
 * menuItems: EuiMenuItem[] = [
 *   { id: '1', label: 'Dashboard', url: '/dashboard', icon: 'eui-home' },
 *   { id: '2', label: 'Settings', children: [
 *     { id: '2-1', label: 'Profile', url: '/settings/profile' },
 *     { id: '2-2', label: 'Security', url: '/settings/security' }
 *   ]}
 * ];
 * ```
 *
 * ```html
 * <eui-menu [items]="menuItems" [hasIcons]="true"></eui-menu>
 * ```
 *
 * ### With Filter
 * ```html
 * <eui-menu [items]="menuItems" [hasFilter]="true" searchFilterLabel="Search menu"></eui-menu>
 * ```
 *
 * ### Collapsed Mode
 * ```html
 * <eui-menu [items]="menuItems" [isCollapsed]="true" [hasTooltip]="true"></eui-menu>
 * ```
 *
 * ### Accessibility
 * - Full keyboard navigation with Arrow keys, Enter, and Space
 * - ARIA roles and properties for menu structure
 * - Focus management for nested items
 * - Screen reader announcements for expand/collapse states
 *
 * ### Notes
 * - Supports URL navigation, router links, and command callbacks
 * - Automatically expands to active route when `hasScrollToItem` is enabled
 * - Filter functionality searches through all menu levels
 * - Collapsed mode shows icons or initials with tooltips
