Angular 14 ngx-contextmenu Example to Create Context Menu in HTML Elements Using TypeScript

Welcome folks today in this blog post we will be using the ngx-contextmenu library in angular 14 to create context menu in html elements using typescript in browser. All the full source code of the application is shown below.

Get Started

In order to get started you need to make a new angular project using the below command as shown below

ng new sampleproject

cd sampleproject

And after that you need to install the below libraries using the below command as shown below

npm i ngx-contextmenu

And after that you will see the below directory structure of the angular app as shown below

And now you need to go to app.module.ts file and include the module as shown below

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';
import { ContextMenuModule } from 'ngx-contextmenu';

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

@NgModule({
  imports:      [ BrowserModule, FormsModule, ContextMenuModule.forRoot() ],
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }

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

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

import { FormsModule } from '@angular/forms';

import { ContextMenuModule } from 'ngx-contextmenu';

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

@NgModule({

imports: [ BrowserModule, FormsModule, ContextMenuModule.forRoot() ],

declarations: [ AppComponent ],

bootstrap: [ AppComponent ]

})

export class AppModule { }

As you can see we are including the ContextMenuModule from the ngx-contextmenu library and adding it inside the imports array as shown above.

And now we need to go to app.component.html file and copy paste the following code

app.component.html

<p>
  Right click on someone's name:
</p>
<ul>
    <li *ngFor="let item of items" [contextMenu]="basicMenu" [contextMenuSubject]="item">{{item?.name}}</li>
</ul>
<context-menu>
  <ng-template contextMenuItem (execute)="showMessage('Hi, ' + $event.item.name)">
    Say hi!
  </ng-template>
  <ng-template contextMenuItem divider="true"></ng-template>
  <ng-template contextMenuItem let-item (execute)="showMessage($event.item.name + ' said: ' + $event.item.otherProperty)">
    Bye, {{item?.name}}
  </ng-template>
  <!-- <ng-template contextMenuItem passive="true">
    Input something: <input type="text">
  </ng-template> -->
</context-menu>

<p>

Right click on someone's name:

</p>

<ul>

</ul>

<context-menu>

<ng-template contextMenuItem (execute)="showMessage('Hi, ' + $event.item.name)">

Say hi!

</ng-template>

<ng-template contextMenuItem divider="true"></ng-template>

<ng-template contextMenuItem let-item (execute)="showMessage($event.item.name + ' said: ' + $event.item.otherProperty)">

Bye, {{item?.name}}

</ng-template>

<!-- <ng-template contextMenuItem passive="true">

Input something: <input type="text">

</ng-template> -->

</context-menu>

As you can see in the above html code we are using the ngFor directive to loop through the list items and inside it we are adding the context menu directive and we have the template of the menu in which we have the two options in between we also have the divider of the menu. And also we have binded onclick event listener to the menu as well. Now we need to define this menu items and the methods inside the typescript code as shown below.

And now we need to go to app.component.ts file and copy paste the following code

app.component.ts

import { Component, ViewChild } from '@angular/core';
import { ContextMenuComponent } from 'ngx-contextmenu';

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})
export class AppComponent  {
  name = 'Angular';
  public items = [
      { name: 'John', otherProperty: 'Foo' },
      { name: 'Joe', otherProperty: 'Bar' }
  ];
  @ViewChild(ContextMenuComponent) public basicMenu: ContextMenuComponent;

  showMessage(message: any) {
    console.log(message);
  }
}

import { Component, ViewChild } from '@angular/core';

import { ContextMenuComponent } from 'ngx-contextmenu';

@Component({

selector: 'my-app',

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

styleUrls: [ './app.component.css' ]

})

export class AppComponent {

name = 'Angular';

public items = [

{ name: 'John', otherProperty: 'Foo' },

{ name: 'Joe', otherProperty: 'Bar' }

];

@ViewChild(ContextMenuComponent) public basicMenu: ContextMenuComponent;

showMessage(message: any) {

console.log(message);

}

As you can see we are importing the ContextMenuComponent from the ngx-contextmenu library and then we have declared the array of items and inside it we have two objects. Each object contains the name and then otherProperty values. And then we are defining the showMessage() method and inside it we are printing the message inside the console.
