TieredMenu Using Prime NG

In this article, we will learn how to use tiered menu using PrimeNG in angular.

– First of all, we have to create a Angular application.

– TieredMenu displays submenus in nested overlays.

– TieredMenu uses the common menumodel api to define its items, visit MenuModel API for details.

– First need to add the below code in app.module.ts file

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import {RouterModule} from '@angular/router';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';

import { AppComponent }   from './app.component';

import { TieredMenuModule } from 'primeng/tieredmenu';
import { ButtonModule } from 'primeng/button';

@NgModule({
  imports: [
    BrowserModule,
    BrowserAnimationsModule,
    TieredMenuModule,
    ButtonModule
  ],
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ]
})

export class AppModule { }

– Now we have to add the below code in app.component.ts file

import { Component,OnInit,ViewEncapsulation } from '@angular/core';
import {MenuItem} from 'primeng/api';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html'
})
export class AppComponent { 
    items: MenuItem[];

    ngOnInit() {
        this.items = [
            {
               label:'File',
               icon:'pi pi-fw pi-file',
               items:[
                  {
                     label:'New',
                     icon:'pi pi-fw pi-plus',
                     items:[
                        {
                           label:'Bookmark',
                           icon:'pi pi-fw pi-bookmark'
                        },
                        {
                           label:'Video',
                           icon:'pi pi-fw pi-video'
                        },

                     ]
                  },
                  {
                     label:'Delete',
                     icon:'pi pi-fw pi-trash'
                  },
                  {
                     separator:true
                  },
                  {
                     label:'Export',
                     icon:'pi pi-fw pi-external-link'
                  }
               ]
            },
            {
               label:'Edit',
               icon:'pi pi-fw pi-pencil',
               items:[
                  {
                     label:'Left',
                     icon:'pi pi-fw pi-align-left'
                  },
                  {
                     label:'Right',
                     icon:'pi pi-fw pi-align-right'
                  },
                  {
                     label:'Center',
                     icon:'pi pi-fw pi-align-center'
                  },
                  {
                     label:'Justify',
                     icon:'pi pi-fw pi-align-justify'
                  },

               ]
            },
            {
               label:'Users',
               icon:'pi pi-fw pi-user',
               items:[
                  {
                     label:'New',
                     icon:'pi pi-fw pi-user-plus',

                  },
                  {
                     label:'Delete',
                     icon:'pi pi-fw pi-user-minus',

                  },
                  {
                     label:'Search',
                     icon:'pi pi-fw pi-users',
                     items:[
                        {
                           label:'Filter',
                           icon:'pi pi-fw pi-filter',
                           items:[
                              {
                                 label:'Print',
                                 icon:'pi pi-fw pi-print'
                              }
                           ]
                        },
                        {
                           icon:'pi pi-fw pi-bars',
                           label:'List'
                        }
                     ]
                  }
               ]
            },
            {
               label:'Events',
               icon:'pi pi-fw pi-calendar',
               items:[
                  {
                     label:'Edit',
                     icon:'pi pi-fw pi-pencil',
                     items:[
                        {
                           label:'Save',
                           icon:'pi pi-fw pi-calendar-plus'
                        },
                        {
                           label:'Delete',
                           icon:'pi pi-fw pi-calendar-minus'
                        },

                     ]
                  },
                  {
                     label:'Archieve',
                     icon:'pi pi-fw pi-calendar-times',
                     items:[
                        {
                           label:'Remove',
                           icon:'pi pi-fw pi-calendar-minus'
                        }
                     ]
                  }
               ]
            },
            {
               separator:true
            },
            {
               label:'Quit',
               icon:'pi pi-fw pi-power-off'
            }
        ];
    }
}

– Than add the below code in app.component.html file

<button #btn type="button" pButton icon="pi pi-bars" label="Show" (click)="menu.toggle($event)"></button>
<p-tieredMenu #menu [model]="items" [popup]="true"></p-tieredMenu>
