enableRipple(true);

@Component({
  imports: [MenuModule],
  standalone: true,
  selector: 'app-root',
  template: `<ejs-menu [items]="menuItems"></ejs-menu>`
})
export class AppComponent {
  public menuItems: MenuItemModel[] = [
    {
      text: 'File',
      items: [
        { text: 'Open' },

};

Use in template: <ejs-menu [animationSettings]="animationSettings"></ejs-menu>

3. Menu with Events

public onItemSelect(args: MenuEventArgs): void {
  console.log('Selected item:', args.item.text);
}

Use in template: <ejs-menu (select)="onItemSelect($event)"></ejs-menu>

4. Dynamic Menu Modification

@ViewChild('menu')
public menuObj?: MenuComponent;

public addItem(): void {
  const newItem: MenuItemModel[] = [
    { text: 'New Menu Item' }
  ];
  this.menuObj?.insertAfter(newItem, 'File', false);
}
