When I press header , all cards expand. I have fetch data from API and need to show in a card list

Here I have attached my code. What is the solution to just expand the card which I only pressing?

<div *ngFor="let edsrecord of listofEDS">
        <div class="available_data_sources_block" id="accordion">
          <div class="card">
            <div class="card-header" id="headingOne">
              <h5 class="mb-0">
                <button class="btn btn-link" data-toggle="collapse" data-target="#collapseOne" aria-expanded="true"
                  aria-controls="collapseOne">
                  {{edsrecord.dataSources[0].ERPName.toString()}}
                </button>
              </h5>
            </div>

            <div id="collapseOne" class="collapse show" aria-labelledby="headingOne" data-parent="#accordion">
              <div class="card-body">
                Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. 3 wolf

            </div>
          </div>
        </div>
      </div>

Solution

You did not specify, but from the looks of the code I assume you use bootstrap to do this card action.

Bootstrap assumes, that data-target gets the id of the card which should be opened/closed.

In your example, every button and card has the same data-target/id combo. That is the cause of your error. In Order to fix this, every card need a unique id.

This might sound easy, however I did not get it to work when dynamically assigning values to the properties.

Here is an working example https://stackblitz.com/edit/angular-ivy-eqskk3

First is used a workaround with ngClass.

In a second attempt I did it with jQuery just like bootstrap would provided in the documentation https://getbootstrap.com/docs/4.6/components/collapse/#via-javascript

If you want this functionality out of the box without so much trouble, i would suggest you take a look at https://material.angular.io/components/expansion/
