I had written double ion-virtual-scroll by using component with dynamic ion-item height. I did provided the actual item height for each virtual scroll item.
But the inner Ion-virtual-scroll doesn’t render properly.
The inner loop can be render properly by just using ngFor, but my list might having long item, therefore ngfor is not applicable in my case.
Here is my example https://stackblitz.com/edit/ionic-angular-v5-virtual-scroll-issue-auqqvo
