Example 1: This basic example illustrates how to use the Angular PrimeNG TabView Properties using the activeIndex property.

• app.component.html:

HTML

<h2 style="color: green">
  GeeksforGeeks
</h2>
<h4>
  Angular PrimeNG Tabview Properties
</h4>

<p-tabView [(activeIndex)]="index">
    <p-tabPanel [header]="item.header"

                [selected]="i == 0">
        {{ item.content }}
    </p-tabPanel>
</p-tabView>

• app.component.ts:

Javascript

import { Component, OnInit } from '@angular/core';

@Component({
    selector: 'app-root',
    templateUrl: './app.component.html',
    providers: [],
})
export class AppComponent {
    constructor() { }

    ngOnInit() { }
    items = [
        { header: 'ReactJS', content: 'Learn React JS on GfG' },
        { header: 'AngularJS', content: 'Learn Angular JS on GfG' },
        { header: 'NodeJS', content: 'Learn Node JS on GfG' },
    ];
}

• app.module.ts:

Javascript

import { NgModule } from '@angular/core';
import { BrowserModule }
    from '@angular/platform-browser';
import { RouterModule } from '@angular/router';
import { BrowserAnimationsModule }
    from '@angular/platform-browser/animations';
import { AppComponent } from './app.component';
import { TabViewModule } from 'primeng/tabview';
import { ButtonModule } from 'primeng/button';

@NgModule({
    imports: [
        BrowserModule,
        BrowserAnimationsModule,
        TabViewModule,
        ButtonModule,
        RouterModule.forRoot([
            { path: '', component: AppComponent }
        ])
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
