This section explains how to create a simple ContextMenu, and demonstrate the basic usage of the ContextMenu component in an Angular environment.
The list of dependencies required to use the 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-buttonsYou can use Angular CLI to setup your Angular applications. To install Angular CLI use the following command.
npm install -g @angular/cliStart a new Angular application using below Angular CLI command.
ng new my-app
cd my-appTo install ContextMenu package, use the following command.
npm install @syncfusion/ej2-angular-navigations --saveThe above package installs ContextMenu dependencies which are required to render the component in the Angular environment.
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 { }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'
}];
}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;
}Run the application in the browser using the following command:
ng serveThe 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);
/**

*/
@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 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);
/**

import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);The
separatorproperty should not be given along with the other fields in theMenuItem.
