Example 1: This is the basic example that illustrates how to use the Angular PrimeNG PanelMenu Properties.

• app.component.html:

HTML

<h1 style="color: green">GeeksforGeeks</h1>
<h5>Angualar PrimeNG PanelMenu Properties</h5>
<p-panelMenu [model]="gfg"></p-panelMenu>

• app.component.ts:

Javascript

    templateUrl: './app.component.html',
})

export class AppComponent {
    gfg: MenuItem[];

    ngOnInit() {
        this.gfg = [
            {
              label: 'HTML',
              items: [
                  {

              ],
            },
        ];
    }
}

• app.module.ts:

Javascript

import { NgModule } from '@angular/core';

import { BrowserAnimationsModule }
    from '@angular/platform-browser/animations';
import { AppComponent }   from './app.component';
