 * ```html
 * <epag-page-menu [menuItems]="tabs">
 *   <ng-template pageMenuItem="overview">
 *     <h2>Overview Content</h2>
 *   </ng-template>
 *   <ng-template pageMenuItem="details">

 *   </ng-template>
 * </epag-page-menu>

 * tabs: PageMenuItem[] = [

 *   { label: 'Details', name: 'details' }
 * ];
