Here is the code snippet I am currently working with:
<button *ngFor="let group of groupsList" attr.data-index="{{ group.index }}" (click)="processGroups(group.index)">{{ group.title }}</button>
I am trying to figure out if it is possible to dynamically add a class called clicked to the button that is currently being clicked on. And then, remove the class if another button is clicked?
To make use of ngFor with the index and apply different classes using [class.xxx], follow this structure:
<button [class.clicked]="clickedButton == i"
*ngFor="let group of groupsList let i=index"
attr.data-index="{{ group.index }}"
(click)="clickedButton = i; processGroups(group.index)">
{{ group.title }}</button>
