Angular PrimeNG PickList Templates

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. It provides a lot of templates, components, theme design, an extensive icon library, and much more. In this article, we will see the Angular PrimeNG PickList Templates.

The PickList Component is used to reorder items between different categories and lets us pick and select items. It acts as a drag-and-drop component with two tables and contents in it.

Angular PrimeNG PickList Templates:

• item: Items in the picklist.
• index: Index of the item.
• sourceHeader: For creating headers in the source picklist.
• targetHeader: For creating headers in the target picklist.
• sourceFilter:  For creating a filter in the source picklist.
• targetFilter: For creating a filter in the target picklist.
• emptymessagesource: For creating an empty message in the source picklist.
• emptyfiltermessagesource: For creating an empty filter message in the source picklist.
• emptymessagetarget: For creating an empty message in the target picklist.
• emptyfiltermessagetarget: For creating an empty filter message in the target picklist.

Syntax:

<p-pickList 
    sourceHeader="...." 
    targetHeader="....">

Example 1: Below is the simple code that illustrates the use of the Angular PrimeNG Piclist Template. In this example, we will learn about sourceHeader and targetHeader.

• app.component.html:

HTML

<h1 style="color: green;">
    GeeksforGeeks
</h1>
<h3>
  Angular PrimeNG Picklist Template
</h3>
<p-pickList
    sourceHeader="Hi Geek! I am a Source Header"
    targetHeader="Hi Geek! I am a Target Header" >
</p-pickList>

• app.component.ts:

Javascript

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

@Component({
      selector: 'app-root',
      templateUrl: './app.component.html'
})

export class AppComponent { }

• app.module.ts:

Javascript

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import {FormsModule} from '@angular/forms';
import { HttpClientModule } from '@angular/common/http';
import { BrowserAnimationsModule }
    from '@angular/platform-browser/animations';
import { AppComponent }   from './app.component';
import { ProductService } from './productservice';
import {PickListModule} from 'primeng/picklist';

@NgModule({
    imports: [
        BrowserModule,
        BrowserAnimationsModule,
        PickListModule,
        HttpClientModule,
        FormsModule
    ],
    declarations: [ AppComponent ],
    bootstrap:    [ AppComponent ],
    providers: [ProductService]
})

export class AppModule { }
