Angular 11 PrimeNG Expand Collapse Data Table Row Working Demo

Hello friends, welcome back to my blog. Today this blog post will tell you, Angular 11 PrimeNG Expand Collapse Data Table Row Working Demo.

About Working: In this post, I am doing PrimeNG Data Table row expand collapse functionality. I am getting dynamic data for demo working. I will also come with more good demos. Please share your queries related to PrimeNG Data Table.

Guys for testing PrimeNG table with dynamic data, please use this WEB API.

Angular 11 came and Bootstrap 5 also and very soon Angular 12 will come and if you are new then you must check below two links:

1. Angular11 Basic Tutorials
2. PrimeNG
3. Bootstrap 5

Friends now I proceed onwards and here is the working code snippet and please use carefully this to avoid the mistakes:

1. Firstly friends we need fresh angular 11 setup and for this we need to run below commands but if you already have angular 11 setup then you can avoid below commands. Secondly we should also have latest node version installed on our system:

npm install -g @angular/cli 

ng new angularprimeng //Create new Angular Project

cd angularprimeng // Go inside the Angular Project Folder

2. Now friends we need to run below commands into our project terminal to install primeng  modules into our angular application:

npm install primeng --save

npm install primeicons --save 

npm install @angular/cdk --save

npm install primeflex --save //for flex layout

3. Now friends we just need to add below code into angularprimeng/src/app/app.component.html file to get final out on the web browser:

<div class="card">
    <h1 class="p-text-center">Angular 11 PrimeNG Expand/Collapse Data Table Row Working</h1>
   
  <p-table #dt2 [value]="customers" dataKey="id"
      [rows]="5" [showCurrentPageReport]="true" [rowsPerPageOptions]="[5,10,15]" [loading]="loading" styleClass="p-datatable-customers p-datatable-gridlines"
      [paginator]="true" currentPageReportTemplate="Showing {first} to {last} of {totalRecords} entries"
      [globalFilterFields]="['name','customers.name']">
      <ng-template pTemplate="caption">
        <div class="p-d-flex">
            <span class="p-input-icon-left p-ml-auto">
                <i class="pi pi-search"></i>
                <input class="p-inputtext p-component" pInputText type="text" (input)="dt2.filterGlobal($event.target.value, 'contains')" placeholder="Search Name" />
            </span>
        </div>
    </ng-template>
      <ng-template pTemplate="header">
        <tr>

                    <p-columnFilter type="text" field="name" display="menu"></p-columnFilter>
                </div>
            </th>
              <th>
                <div class="p-d-flex p-jc-between p-ai-center">
                    Email

                </div>
              </th>
              <th>Job Title</th>

              
          </tr>
         
      </ng-template>
      <ng-template pTemplate="body" let-customer let-expanded="expanded">
          <tr>
            <td>
                <button type="button" pButton pRipple [pRowToggler]="customer" class="p-button-text p-button-rounded p-button-plain" [icon]="expanded ? 'pi pi-chevron-down' : 'pi pi-chevron-right'"></button>
            </td>
              <td>
                  {{customer.name}}
              </td>
              <td>
                 
                  {{customer.email}}
              </td>
              
              <td>
                   {{customer.job_title}}
              </td>
              
          </tr>
      </ng-template>
      <ng-template pTemplate="emptymessage">
          <tr>
              <td colspan="5">No customers found.</td>
          </tr>
      </ng-template>

      <!--Expand Row-->
      <ng-template pTemplate="rowexpansion">
        <tr>
            <td colspan="4">
                <div class="p-p-3">
                    <p-table [value]="customers" dataKey="id">
                        <ng-template pTemplate="header">
                            <tr>
                                <th pSortableColumn="job_title">Job Title<p-sortIcon field="job_title"></p-sortIcon> </th>
                               
                           
                               
                            </tr>
                        </ng-template>
                        <ng-template pTemplate="body" let-customer>
                            <tr>
                                <td> {{customer.job_title}}</td>
                                
                               
                               
                            </tr>
                        </ng-template>
                        <ng-template pTemplate="emptymessage">
                            <tr cl>
                                <td class="p-text-center" colspan="3">There are no data for this user yet.</td>
                            </tr>
                        </ng-template>
                    </p-table>
                </div>
            </td>
        </tr>
    </ng-template>
  </p-table>
</div>

4. Now friends we just need to add below code into angularprimeng/angular.json file:

 "styles": [
              "src/styles.css",
              "node_modules/primeng/resources/themes/saga-blue/theme.css",
              "node_modules/primeng/resources/primeng.min.css",
              "node_modules/primeflex/primeflex.css",
              "node_modules/primeicons/primeicons.css",
            ],
...

5. Now friends we just need to add below code into angularprimeng/src/app/app.component.ts file:

...
import { HttpClient } from '@angular/common/http';
export class AppComponent {
  
  //data variable
  customers:any;
  loading: boolean = true;
  constructor(private http: HttpClient){
    //get request from web api and you can also use this web api for testing

    this.http.get('https://www.testjsonapi.com/users/').subscribe(data => {
      //data storing for use in html component
      this.loading = false;
      this.customers = data;
          }, error => console.error(error));
  }
  ngOnInit() {
   

  
}

}

6. Now friends we just need to add below code into angularprimeng/src/app/app.module.ts file:

...
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import {TableModule} from 'primeng/table';
import {DropdownModule} from 'primeng/dropdown';
import { HttpClientModule } from '@angular/common/http';
import {ButtonModule} from 'primeng/button';

@NgModule({
 ...
  imports: [
   ...
    BrowserAnimationsModule,
    TableModule,
    DropdownModule,
    HttpClientModule,
    ButtonModule
  ],
  ...

Friends in the end must run ng serve command into your terminal to run the angular 11 project.

Now we are done friends. If you have any kind of query, suggestion and new requirement then feel free to comment below.
