Example 1: This is the basic example that shows how to use the TabMenu component.

app.component.html

<h2>GeeksforGeeks</h2>
<h5>PrimeNG TabMenu Component</h5>
<p-tabMenu [model]="gfg"></p-tabMenu>

app.component.ts

import { Component } from '@angular/core';
import { MenuItem } from 'primeng/api';

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

  ngOnInit() {
    this.gfg = [
      {
        label: 'HTML'
      },
      {
        label: 'AngularJS'
      },
      {
        label: 'ReactJS'
      },
      {
        label: 'PrimeNG'
      }
    ];
  }
}

app.module.ts

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 { TabMenuModule } from 'primeng/tabmenu';

@NgModule({
  imports: [
    BrowserModule,
    BrowserAnimationsModule,
    TabMenuModule,
    RouterModule.forRoot([{ path: '',
                    component: AppComponent }])
  ],
  declarations: [AppComponent],
  bootstrap: [AppComponent]
})
export class AppModule {}

Output:

Example 2: In this example, the first item ie., HTML, in this case, will be pre-selected while loading the page for the first time.

app.component.html

<h2>GeeksforGeeks</h2>
<h5>PrimeNG TabMenu Component</h5>
<p-tabMenu [model]="gfg" [activeItem]="activeItem"></p-tabMenu>

app.component.ts

import { Component } from '@angular/core';
import { MenuItem } from 'primeng/api';

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

  activeItem: MenuItem;

  ngOnInit() {
    this.gfg = [
      {
        label: 'HTML'
      },
      {
        label: 'AngularJS'
      },
      {
        label: 'ReactJS'
      },
      {
        label: 'PrimeNG'
      }
    ];

    this.activeItem = this.gfg[0];
  }
}

app.module.ts

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 { TabMenuModule } from 'primeng/tabmenu';

@NgModule({
  imports: [
    BrowserModule,
    BrowserAnimationsModule,
    TabMenuModule,
    RouterModule.forRoot([{ path: '',
                  component: AppComponent }])
  ],
  declarations: [AppComponent],
  bootstrap: [AppComponent]
})
export class AppModule {}
