Trying to keep Ion-Select interface popover open after selection

Is there a way to keep the ion-select open after clicking on a ion-select-option, i am using popover interface for the IonSelect.

  value="{{ selectedValue?.fileName }}"
    *ngFor="let tone of items"
    value="{{ tone.fileName }}"
    >{{ }}</ion-select-option

When a user clicks on an ion-select-option i am trying to trigger onToneClick() but not close the popover.

using Ionic Framework : @ionic/angular 5.6.12

I think this is where you should be setting your popover options, like the PopoverController
