Horizontal scrolling programmatically

Ionic Framework ionic-v3
1

Hi guys,
I have ion-scroll in my app and I’d like to scroll automatically when user trigger an event.

My code:

  <ion-toolbar>
    <ion-scroll scrollX="true" scrollY="false">
      <p *ngFor="let level of levels ; let i=index" [id]="level.id" (click)="changeTab(i,level)">
        {{level.label}}
      </p>
    </ion-scroll>
  </ion-toolbar>

levels in an array of level objects. it is an example:

{
  "id": x,
  "label": "abc"
}

When my page show I need to init my toolbar moving on exactly item.

I’d like center the item on the scrollbar, moving for example on the right.

Could you please help me?

Thanks
Luca
