I have the below code which i am using to expand or collapse the elements

<div class="accordion" (click)="toggleAccordian($event, i)">

clickMenu(event: any, index: any) {
    var element = event.target;

    let elements = this.divElements.nativeElement.querySelectorAll('.sub');

    for (var i = 0; i < elements.length; i++) {
      elements[i].classList.remove('subactive');
    }

  }

Now i want to call clickMenu from ngInIt event. How do i pass $event
