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 Overlay in Angular PrimeNG.

Angular PrimeNG Menu Overlay can show the menu as a popup. By default, the menu is inline, but popup mode can 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 Overlay 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.

Creating Angular application & module installation:

Step 1: Create an Angular application using the following command.

ng new appname

Step 2: After creating your project folder i.e. appname, move to it using the following command.

cd appname

Step 3: Install PrimeNG in your given directory.

npm install primeng --save
npm install primeicons --save

Project Structure: After the complete installation, it will look like the following:

 

  • Run the below command to see the output:
ng serve --open

Example 1: Below is the example that illustrates the use of Angular PrimeNG Menu Overlay.

app.component.html




<h2 style="color: green">GeeksforGeeks</h2>
<h5>Angular PrimeNG Menu Overlay</h5>
<p-menu #menu [popup]="true" 
              [model]="items">
</p-menu>
<button type="button"
        pButton label="GfG Courses" 
        (click)="menu.toggle($event)"> 
</button>

app.component.ts




import { Component } from "@angular/core";
import { MenuItem, MessageService, PrimeNGConfig } from "primeng/api";
  
@Component({
  selector: "my-app",
  templateUrl: "./app.component.html",
  providers: [MessageService],
})
export class AppComponent {
  items: MenuItem[];
  
  constructor(
    private messageService: MessageService,
    private primengConfig: PrimeNGConfig
  ) {}
  
  ngOnInit() {
    this.primengConfig.ripple = true;
  
    this.items = [
      {
        label: "GeeksforGeeks Courses",
        items: [
          {
            label: "Data Structure - Self Paced",
            icon: "pi pi-code",
          },
          {
            label: "Complete Interview Preparation",
            icon: "pi pi-globe",
          },
        ],
      },
    ];
  }
}

app.module.ts




import { NgModule } from "@angular/core";
import { BrowserModule } from "@angular/platform-browser";
import { BrowserAnimationsModule } 
    from "@angular/platform-browser/animations";
  
import { AppComponent } from "./app.component";
import { MenuModule } from "primeng/menu";
import { ButtonModule } from "primeng/button";
  
@NgModule({
  imports: [
    BrowserModule, 
      BrowserAnimationsModule, 
      MenuModule, 
      ButtonModule],
  declarations: [AppComponent],
  bootstrap: [AppComponent],
})
export class AppModule {}

  templateUrl: "./app.component.html",
  providers: [MessageService],
})
export class AppComponent {
  items: MenuItem[];
  
  constructor(
    private messageService: MessageService,
    private primengConfig: PrimeNGConfig
  ) {}
  
  ngOnInit() {
    this.primengConfig.ripple = true;
  
    this.items = [
      {
