Add or remove context menu items in Angular Context menu component

6 Sep 20224 minutes to read

ContextMenu items can be added or removed using the insertAfter, insertBefore and removeItems methods.

In the following example, the Display Settings menu items are added before the Personalize item, the Sort By menu items are added after the Refresh, and the Paste item is removed from context menu.

app.component.ts

import { Component, ViewChild } from '@angular/core';
import { ContextMenuComponent, MenuEventArgs, MenuItemModel } from '@syncfusion/ej2-angular-navigations';

@Component({
  selector: 'app-root',
  template: `<!--target element-->
            <div id="target">Right click / Touch hold to open the ContextMenu</div>
            <!-- To Render ContextMenu. -->
            <ejs-contextmenu #contextmenu target='#target' [items]='menuItems' (created)='onCreated()'></ejs-contextmenu>`
})

export class AppComponent {
     @ViewChild('contextmenu')
    public contextmenu: ContextMenuComponent;

    public menuItems: MenuItemModel[] = [
    {
        text: 'View',
        items: [
          {
            text: 'Large icons'
          },
          {
            text: 'Medium icons'
          },
          {
            text: 'Small icons'
          }
        ]
    },
    {
        text: 'Refresh'
    },
    {
        text: 'Paste'
    },
    {
        separator: true
    },
    {
        text: 'New'
    },
    {
        separator: true
    },
    {
        text: 'Personalize'
    }];

    onCreated(): void {
      this.contextmenu.insertAfter([{text: 'Sort By'}] , 'Refresh');
      this.contextmenu.insertBefore([{text: 'Display Settings'}] , 'Personalize');
      this.contextmenu.removeItems(['Paste']);
    }

}

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { ContextMenuModule } from '@syncfusion/ej2-angular-navigations';
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);

main.ts

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);
