Example 1: Below is the code example that illustrates the use of Angular PrimeNG Dialog Header and Footer using the pTemplate=”header”.

app.component.html

<div style="text-align: center">
  <h2 style="color: green">GeeksforGeeks</h2>
  <h5>PrimeNG Dialog Header and Footer</h5>

  <p-dialog position="center"
            header="GeeksforGeeks"
            [(visible)]="geeks">
    <ng-template pTemplate="header">
        Hey Geek, I'm the header!
    </ng-template>
    <p>
        Hi GfG you are the complete
        computer science portal for geeks.
    </p>
  </p-dialog>

  <p-button (click)="gfg()"
            label="Click Here">
  </p-button>
</div>

app.component.ts

import { Component } from "@angular/core";
import { PrimeNGConfig } from "primeng/api";

@Component({
  selector: "app-root",
  templateUrl: "./app.component.html",
})
export class AppComponent {
  constructor(private primengConfig: PrimeNGConfig) {}

  ngOnInit() {
    this.primengConfig.ripple = true;
  }
  geeks: boolean;

  gfg() {
    this.geeks = true;
  }
}

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 { DialogModule } from "primeng/dialog";
import { ButtonModule } from "primeng/button";

@NgModule({
  imports: [BrowserModule,
              BrowserAnimationsModule,
              DialogModule,
              ButtonModule],
  declarations: [AppComponent],
