Step 5

Configure PrimeNG module in the app.module.ts file. Let's import the required module in this file.

App.module.ts fille

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { BrowserAnimationsModule } from "@angular/platform-browser/animations";
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { AccordionModule } from 'primeng/components/accordion/accordion';
import {OrderListModule} from 'primeng/orderlist';
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
AppRoutingModule,BrowserAnimationsModule,AccordionModule,OrderListModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }

Step 7

Now, open app.component.html and add PrimeNG accordion, a list. Add the following lines in this file.

<p-accordion>
<p-accordionTab header="India">
<p-orderList [value]="Indiastate">
<ng-template let-state pTemplate="item">
<div class="ui-helper-clearfix">
<div style="font-size:16px;float:left;margin:5px">{{state}}</div>
</div>
</ng-template>
</p-orderList>
</p-accordionTab>
<p-accordionTab header="Australia">
<p-orderList [value]="Ausstate">
<ng-template let-Ausstate pTemplate="item">
<div class="ui-helper-clearfix">
<div style="font-size:16px;float:left;margin:5px">{{Ausstate}}</div>
</div>
</ng-template>
</p-orderList>
</p-accordionTab>
<p-accordionTab header="SriLanka">

<ng-template let-Slstate pTemplate="item">
<div class="ui-helper-clearfix">
<div style="font-size:16px;float:center;margin:5px">{{Slstate}}</div>
</div>
</ng-template>
</p-orderList>
</p-accordionTab>
</p-accordion>

Step 8

Open app.component.ts file and add the following code.

import { Component } from '@angular/core';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
Indiastate = [
"Rajasthan",
"UP",
"Mp",
"Delhi",
"Goa",
"Gurjat",

Ausstate = [
"New South Wales",

"South Australia",
"Tasmania"
];
Slstate = [

"Galle",
"Kegalle",
"Mannar"
];
}
