Angular PrimeNG is an open-source framework with a rich set of native Angular UI components that are used for great styling and this framework is used to make responsive websites with very much ease. In this article, we will know how to use the TabView component in Angular PrimeNG. We will also learn about the properties, events, styling along with their syntaxes that will be used in the code.

• p-tabview-selected: It is the selected tab header.
• p-tabview-panels: It is the container panels.
• p-tabview-panel: It is the content of a tab.

Creating Angular application & module installation:

• Step 1: Create an Angular application using the following command.

ng new appname

• Step 2: After creating your project folder i.e. appname, move to it using the following command.

cd appname

• Step 3: Install PrimeNG in your given directory.

npm install primeng --save
npm install primeicons --save

Project Structure: It will look like the following:

Example 1: This is the basic example that illustrates how to use the TabView component.

app.component.html

<h2>GeeksforGeeks</h2>
<h5>PrimeNG TabView Component</h5>
<p-tabView>
  <p-tabPanel header="TabView Component">
    <p>Content1</p>
  </p-tabPanel>
  <p-tabPanel header="TabView Component">
    <p>Content2</p>
  </p-tabPanel>
  <p-tabPanel header="TabView Component">
    <p>Content3</p>
  </p-tabPanel>
</p-tabView>

app.component.ts

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

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponent {}

app.module.ts

import { NgModule } from "@angular/core";
import { BrowserModule } from "@angular/platform-browser";
import { BrowserAnimationsModule }
    from "@angular/platform-browser/animations";

import { AppComponent } from "./app.component";
import { TabViewModule } from "primeng/tabview";

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

Output:

Example 2: In this example, we will know how to use closable property in the Tabview component.

app.component.html

<h2>GeeksforGeeks</h2>
<h5>PrimeNG TabView Component</h5>
<p-tabView >
    <p-tabPanel header="TabView Component" closable='true'>
        <p>Content1</p>
    </p-tabPanel>
    <p-tabPanel header="TabView Component" closable='true'>
        <p>Content2</p>
    </p-tabPanel>
    <p-tabPanel header="TabView Component" closable='true'>
        <p>Content3</p>
    </p-tabPanel>
</p-tabView>

app.component.ts

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

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponent {}

app.module.ts

import { NgModule } from "@angular/core";
import { BrowserModule } from "@angular/platform-browser";
import { BrowserAnimationsModule }
    from "@angular/platform-browser/animations";

import { AppComponent } from "./app.component";
import { TabViewModule } from "primeng/tabview";

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