Angular 9 Accordion – Introduction

The Angular 9 Accordion used in this project is created from the Syncfusion `ej2-angular-accordion` package. You can simply define it as <ejs-accordion> within the template.

Dependencies

Creating Angular Project

We will see the Angular project creation steps using the Angular CLI tool.

1. Install the Angular CLI application in your machine.

   npm install -g @angular/cli@9.0.2
   

2. Now create a new Angular project by using the command `ng new` and navigate to that folder.

   ng new <project name>
   cd <project name>
   

3. Install the ej2-angular-navigations package through the npm install command.

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

Adding Angular 9 Accordion

You can add the Angular 9 Accordion component by using `ejs-accordion` directive and the attributes used within this tag allows you to define other accordion functionalities.

1. Import the AccordionModule into app.module.ts file from the ej2-angular-navigations package.
2. The next step in Angular Accordion creation is to import and inject the other required modules within the providers section of app.module.ts.

[app.module.ts]

import { BrowserModule } from '@angular/platform-browser';
import { AccordionModule } from '@syncfusion/ej2-angular-navigations';
import { NgModule } from '@angular/core';
 
import { AppComponent } from './app.component';
 
@NgModule({
    Declarations: [AppComponent],
    imports: [
        BrowserModule, AccordionModule
    ],
    providers: [ ],
    bootstrap: [AppComponent]
})
export class AppModule { }

3. Define the Angular Accordion code within the app.component.html file which is mapped against the templateUrl option in app.component.ts file.

[app.component.html]

<ejs-accordion>
  <e-accordionitems>
    <e-accordionitem expanded='true'>
      <ng-template #header>
        <div>ASP.NET</div>
      </ng-template>
      <ng-template #content>
        <div>Microsoft ASP.NET is a set of technologies in the Microsoft .NET Framework for building Web applications
          and XML Web services.
        </div>
      </ng-template>
    </e-accordionitem>
    <e-accordionitem>
      <ng-template #header>

          the model, the view, and the controller.
        </div>
      </ng-template>
    </e-accordionitem>
    <e-accordionitem>
      <ng-template #header>
        <div>JavaScript</div>
      </ng-template>
      <ng-template #content>
        <div>JavaScript (JS) is an interpreted computer programming language. It was originally implemented as part of
          web browsers so that client-side scripts could interact with the user, control the browser, communicate
          asynchronously, and
          alter the document content that was displayed.
        </div>
      </ng-template>
    </e-accordionitem>
  </e-accordionitems>
</ejs-accordion>
