Angular PrimeNG Menu Popup Mode

Angular PrimeNG is an open-source framework with a rich set of native Angular UI components that are used for great styling and this framework is used to make responsive websites with very much ease. This article will show us how to use the Menu Popup Mode in Angular PrimeNG.

The Menu Popup Mode can be used to show the menu as a popup. By default, the menu is inline, but popup mode can alternatively be used by enabling the popup property and invoking the toggle function with the event passed in from the anchor element.

Syntax:

<p-menu #menu [popup]="true" 
    [model]="items">
</p-menu>

<button type="button" pButton 
    icon="..." label="..." 
    (click)="menu.toggle($event)">
</button>

Angular PrimeNG Menu Popup Mode properties:

• [popup]: It decides whether the menu should be displayed as a popup or not. Its default value is false.
• [model]: It is an array of menu items.

  items: MenuItem[];

  constructor(
    private messageService: MessageService,
    private primengConfig: PrimeNGConfig
  ) {}

  ngOnInit() {
    this.primengConfig.ripple = true;

    this.items = [
      {
