Example 1: Below is the example code that illustrates the use of the Angular PrimeNG Timeline Properties using the align property.

• app.component.html:

HTML

<h1 style="color: green">GeeksforGeeks</h1>
<h4>Angular PrimeNG Timeline align Properties.</h4>

<h5>Align = Left</h5>
<p-timeline [value]="gfg">
    <ng-template pTemplate="content" let-event>
        {{event.status}}
    </ng-template>
</p-timeline>

<h5>Align = Right</h5>
<p-timeline [value]="gfg" align="right">
    <ng-template pTemplate="content" let-event>
        {{event.status}}
    </ng-template>
</p-timeline>

<h5>Align = Alternate</h5>
<p-timeline [value]="gfg" align="alternate">
    <ng-template pTemplate="content" let-event>
        {{event.status}}
    </ng-template>
</p-timeline>

• app.component.ts:

Javascript

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

@Component({
    selector: "app-root",
    templateUrl: "./app.component.html",
    styleUrls: ["./app.component.scss"],
})

export class AppComponent {
    gfg: any[];

    ngOnInit() {
      this.gfg = [
          {
            status: "Geek 1",
          },
          {
            status: "Geek 2",
          },
          {
            status: "Geek 3",
          },
          {
            status: "Geek 4",
          },
        ];
    }
}

• app.module.ts:

Javascript

import { NgModule } from '@angular/core';
import { BrowserModule }
    from '@angular/platform-browser';
import { BrowserAnimationsModule }
    from '@angular/platform-browser/animations';
import { FormsModule } from '@angular/forms';
import { TimelineModule } from 'primeng/timeline';
import { CardModule } from 'primeng/card';
import { ButtonModule } from 'primeng/button';
import { AppComponent } from './app.component';

@NgModule({
    imports: [
        BrowserModule,
        BrowserAnimationsModule,
        FormsModule,
        ButtonModule,
        TimelineModule,
        CardModule,
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
})

export class AppModule {}

Output:

Example 2: Below is another example code that illustrates the use of the Angular PrimeNG Timeline Properties using the layout=”horizontal” property.

• app.component.html:

<h4>Angular PrimeNG Timeline layout Properties.</h4>

<h6>Align = Top</h6>
<p-timeline [value]="gfg" layout="horizontal" align="top">

</p-timeline>

<h6>Align = Bottom</h6>
<p-timeline [value]="gfg" layout="horizontal" align="bottom">
    <ng-template pTemplate="content" let-event>
        {{event.status}}
    </ng-template>
</p-timeline>

<h6>Align = Alternate</h6>
<p-timeline [value]="gfg" layout="horizontal" align="alternate">
    <ng-template pTemplate="content" let-event>
        {{event.status}}
