Getting started with Angular Context Menu component

This section explains how to create a simple ContextMenu, and demonstrate the basic usage of the ContextMenu component in an Angular environment.

Dependencies

The list of dependencies required to use the Angular ContextMenu component in your application is given below:

|-- @syncfusion/ej2-angular-navigations
    |-- @syncfusion/ej2-angular-base
    |-- @syncfusion/ej2-navigations
        |-- @syncfusion/ej2-base
        |-- @syncfusion/ej2-data
        |-- @syncfusion/ej2-lists
        |-- @syncfusion/ej2-inputs
        |-- @syncfusion/ej2-splitbuttons
        |-- @syncfusion/ej2-popups
            |-- @syncfusion/ej2-buttons

Setup Angular environment

You can use Angular CLI to setup your Angular applications. To install Angular CLI use the following command.

npm install -g @angular/cli

Create an Angular application

Start a new Angular application using below Angular CLI command.

ng new my-app
cd my-app

Installing Syncfusion ContextMenu Package

Syncfusion packages are distributed in npm as @syncfusion scoped packages. You can get all the Angular Syncfusion package from npm link.

Currently, Syncfusion provides two types of package structures for Angular components,

1. Ivy library distribution package format
2. Angular compatibility compiler(Angular’s legacy compilation and rendering pipeline) package.

Ivy library distribution package

Syncfusion Angular packages(>=20.2.36) has been moved to the Ivy distribution to support the Angular Ivy rendering engine and the package are compatible with Angular version 12 and above. To download the package use the below command.

Add @syncfusion/ej2-angular-navigations package to the application.

npm install @syncfusion/ej2-angular-navigations --save

Angular compatibility compiled package(ngcc)

For Angular version below 12, you can use the legacy (ngcc) package of the Syncfusion Angular components. To download the ngcc package use the below.

Add @syncfusion/ej2-angular-navigations@ngcc package to the application.

npm install @syncfusion/ej2-angular-navigations@ngcc --save

To mention the ngcc package in the package.json file, add the suffix -ngcc with the package version as below.

@syncfusion/ej2-angular-navigations:"20.2.38-ngcc"

Note: If the ngcc tag is not specified while installing the package, the Ivy Library Package will be installed and this package will throw a warning.

Adding ContextMenu module

Import ContextMenu module into Angular application(app.module.ts) from the package @syncfusion/ej2-angular-navigations.

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

// Imported Syncfusion contextmenu module from navigations package
import { ContextMenuModule } from '@syncfusion/ej2-angular-navigations';
import { AppComponent }  from './app.component';

@NgModule({
  imports:      [ BrowserModule, ContextMenuModule ], // Registering EJ2 ContextMenu Module
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }

Adding Syncfusion ContextMenu component

Modify the template in app.component.ts file with ejs-contextmenu to render the ContextMenu component and the option contains menuItems and target in which ContextMenu will be opened.

import { Component } from '@angular/core';
import { MenuItemModel } from '@syncfusion/ej2-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 id='contextmenu' target='#target' [items]= 'menuItems'></ejs-contextmenu>`
})

export class AppComponent {
public menuItems: MenuItemModel[] = [
{
    text: 'Cut'
},
{
    text: 'Copy'
},
{
    text: 'Paste'
}];
}

Adding CSS reference

Add ContextMenu component’s styles as given below in style.css.

@import '../node_modules/@syncfusion/ej2-navigations/styles/material.css';

/* Context Menu target */
#target {
border: 1px dashed;
height: 150px;
padding: 10px;
position: relative;
text-align: justify;
color: gray;
user-select: none;
}

Running the application

Run the application in the browser using the following command:

ng serve

The following example shows a basic ContextMenu component.

import { Component } from '@angular/core';
import { MenuItemModel } from '@syncfusion/ej2-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 id='contextmenu' target='#target' [items]= 'menuItems'></ejs-contextmenu>`
})

export class AppComponent {
public menuItems: MenuItemModel[] = [
{
    text: 'Cut'
},
{
    text: 'Copy'
},
{
    text: 'Paste'
}];
}

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);

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule,
        ContextMenuModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule { }

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

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

Rendering items with Separator

The Separators are the horizontal lines used to separate the menu items. You cannot select the separators. You can enable separators to group the menu items using the separator property. Cut, Copy, and Paste menu items are grouped using separator property in the following sample.

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

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

export class AppComponent {
public menuItems: MenuItemModel[] = [
    {
        text: 'Cut'
    },
    {
        text: 'Copy'
    },
    {
        text: 'Paste'
    },
    {
        separator: true
    },
    {
        text: 'Font'
    },
    {
        text: 'Paragraph'
    }
    ];
}

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);

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule,
        ContextMenuModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule { }

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

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

The separator property should not be given along with the other fields in the MenuItem.
