How to disable ,hiding options from dopdown after selection

Am working on angular application with primeng. I need to stop hiding the options of menu dropdown after selecting an option!

<p-menu onchange="onSelected" [showTransitionOptions]="'0ms'" [hideTransitionOptions]="" #menu [popup]="true" 
[model]="items"></p-menu>
        <button type="button" pButton icon="fa fa-fw fa-list" label="Sort" 
(click)="menu.toggle($event)"></button>


  onSortingSelected() {
  event.stopPropagation();
}

How to solve this? I need to click on multiple selection options one at a time without hiding the option list!

this is the PrimaNG code

    itemClick(event, item: MenuItem) {
        if (item.disabled) {
            event.preventDefault();
            return;
        }

        if (!item.url) {
            event.preventDefault();
        }

        if (item.command) {
            item.command({
                originalEvent: event,
                item: item
            });
        }

        if (this.popup) {
            this.hide();
        }
    }

Looks like there's no way to change that behaviour.

One possible solution is to write your component inheriting from the PrimeNG one and override the itemClick implementation

I never tried but .... there's this article that might help
