      Hello,
      I have the hierarchical list (parent->children; 1 level only, no multi-levels) which may contain thousands of items; and I’m using QTree to display it in expanded mode (UI requirement).

      The problem: if the total number of items (both parent and children) is close to 5K - the UI rendering for QTree becomes very slow.

      So the question: is there any way how to provide the virtualization for QTree?

      Quasar Framework provides QVirtualScroll component which is exactly what I need.
      But QVirtualScroll supports list and table only.
      I tried to integrate QVirtualScroll with QTree by few ways but no luck, or I making this incorrectly.

      Any ideas how I could make the virtualization for QTree?
      Or may be some real examples how to use QVirtualScroll with QTree - if it shall work?

      Thanks!

        @baye hi, did u manage to find a solution to this.
        I have the same issue. Tried q-virtual-scroll with the tree but when used together it appears that the tree is defaulted to expanded all … it improves the load but not overall performance…
