I have the below code which displays the icon as part of anchor tag and on click of it , I am showing a list mentioned below with li tag. The problem here is since the li is associated with a single ngFor , say when i=2, the li gets created twice, when i=3, li gets created thrice. How to show only one li at a time and hide others.?

<div *ngFor="let person of persons; let i = index ">

    <div>{{person.name}}</div>

    <a href='#' data-target='dropdown3' class="sharebtn" (click)="shareIconClicked($event, i);"></a>

    <ul id='dropdown3' [ngClass]="{'popupShare': showPopup == true}">

        <li><a>Copy Message</a></li>

    </ul>

</div>
