12 Sep 20257 minutes to read

Sidebar can also be initialized using SystemJS as follows:

Installation and configuration

To set up a basic Angular application with SystemJS:

git clone https://github.com/angular/quickstart.git quickstart
cd quickstart
npm install

For more details, refer to the Angular setup guide.

  • Install Syncfusion® Sidebar package:
npm install @syncfusion/ej2-angular-navigations --save

This installs the Sidebar and its dependencies required for rendering in an Angular environment.

  • Syncfusion ej2-angular-navigations packages need to be mapped in systemjs.config.js configuration file.
/**
 * System configuration for Angular samples
 * Adjust as necessary for your application needs.
 */
(function (global) {
  System.config({
    paths: {
      // paths serve as alias
      'npm:': 'node_modules/',
      "syncfusion:": "node_modules/@syncfusion/", // syncfusion alias

    },
    // map tells the System loader where to look for things
    map: {
      // our app is within the app folder
      'app': 'app',

      rxjs: {

})(this);

Import the Sidebar and dependent component’s styles in style.css:

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

Note: If you want to refer the combined component styles, please make use of our CRG (Custom Resource Generator) in your application.

Create a simple Sidebar

Refer the following code to include the Sidebar in your application .

  • Create an Angular application with Sidebar component. Add the following Sidebar template in component template of app.component.ts 
<ejs-sidebar id="default-sidebar" >
    <div class="title"> Sidebar content</div>
</ejs-sidebar>
<div>
    <div class="title">Main content</div>
    <div class="sub-title">
        Content goes here.
    </div>
</div>
  • Create an Angular module and include the above Sidebar component.
  • In the module, declare the Component and Directives required to render the Sidebar.
  • Bootstrap the application with the above module.

Refer to the following snippet to import the Sidebar module in app.module.ts from the @syncfusion/ej2-angular-navigations.

import { AppComponent } from './app.component';
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { SidebarModule } from '@syncfusion/ej2-angular-navigations';

@NgModule({
    imports: [SidebarModule, BrowserModule],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule { }

systemjs.config.js file should be configured as described in the Installation and configuration section.

Run the application

Use the npm run start command to run the application in the browser.

npm start

The following sample shows the Sidebar component in the browser.

import { BrowserModule } from '@angular/platform-browser'
import { NgModule } from '@angular/core'
import { SidebarModule } from '@syncfusion/ej2-angular-navigations'



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

@Component({
imports: [SidebarModule, ],


standalone: true,
  selector: 'app-root',
  styleUrls: ['./app.component.css'],
  template: ` <ejs-sidebar id="default-sidebar" #sidebar (created)="onCreated($event)" style="visibility: hidden">
                <div class="title"> Sidebar content</div>
              </ejs-sidebar>
              <div>
                <div class="title">Main content</div>
                <div class="sub-title">
                    Content goes here.
                </div>
              </div>`
})
export class AppComponent {
    @ViewChild('sidebar') sidebar?: SidebarComponent;
    public onCreated(args: any) {
      (this.sidebar as SidebarComponent).element.style.visibility = '';
    }
}
@import 'node_modules/@syncfusion/ej2-base/styles/material.css';
@import 'node_modules/@syncfusion/ej2-angular-base/styles/material.css';
@import 'node_modules/@syncfusion/ej2-angular-navigations/styles/material.css';
@import 'node_modules/@syncfusion/ej2-angular-buttons/styles/material.css';
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));
