ngx-bootstrap popover is not working properly

Question

I am using ngx-bootstrap popover . I want the popover should open on hover, and all opened ones should be closed if new one is opened.

working example

As per requirement I want above sample should controlled by parent component and target popover lies in child component. I need this for modularity requirement

Demo ngFor in child component html this is wrong demo

Updated demo ngFor in parent component html

parent component

export class DemoPopoverFourDirectionsComponent  implements 

AfterViewInit{
  @ViewChildren(PopoverDirective) popovers: QueryList<PopoverDirective>;

  ngAfterViewInit() {
    this.popovers.forEach((popover: PopoverDirective) => {
      popover.onShown.subscribe(() => {
        this.popovers
        .filter(p => p !== popover)
        .forEach(p => p.hide());
      });
    });
  }

varArr=[1,2,3,4]

}

In popover there are buttons which need to be clicked. If I use triggers="mouseenter:mouseleave" I cannot click buttons inside the popover

Answer 1

Simply set triggers="mouseenter:mouseleave"

See: https://ng-bootstrap.github.io/#/components/popover/examples#triggers

Update:

Because of new requirements here is a changed version which closes an old popover and let us click a button inside:

HTML

<div *ngFor="let d of varArr; let i = index">
    <button type="button" class="btn btn-default btn-secondary"      
          #pop="bs-popover"
          [popover]="popover"
          popoverTitle="Popover on top"          
          placement="right" triggers="mouseenter"          
          (onShown)="closeOldPopover(pop)"
          [outsideClick]="true">
    Popover on top
  </button>

  <ng-template #popover>
    <button (click)="pop.hide()">Test</button>
  </ng-template>
</div>

TS

private _currentPopover: any;

@Input() varArr;

ngOnInit() {

}

public closeOldPopover(popover: any): void {
  if (this._currentPopover && this._currentPopover !== popover) {
    this._currentPopover.hide();
  }

  this._currentPopover = popover;
}
