- This issue doesn't happen in 220.127.116.11. It starts to happen since 18.104.22.168
- The reported user thinks the previous behavior provides a better user experience because a user can know the range of items while he is dragging.
- <custom-attributes org.zkoss.zul.tree.initRodSize="-1"/> is not an option since the items are too many.
- I have tried <custom-attributes org.zkoss.zul.tree.preloadSize="5"/>, but it doesn't make a tree render while scrolling.
- <custom-attributes org.zkoss.zul.nativebar="false"/> + tree-onrender.js
