Drag n Drop slow

[xeroe]

Hello, Im facing the issue, that the drag n drop functionality is very slow in my application. When moving an item in the tree the "hover effect" is following the movement very slowly like a trail. Did someone experience similar problems or has an idea how to fix this problem?

seems to happen with larger lists in this component. I am now using atlaskit tree in my project, which can handle larger lists

You can virtualize the tree (by passing height and itemHeight to the Tree component) and that helps you a litlle bit (animation example: https://tree-react-component.vercel.app/demo/animation ) => not visible html elements are not rendered

The main problem is that rc-tree makes render after every onDragLeave, onDragOver, onDragEnter, even if you dont define them (whenever you enable draggable)

I found the solution, disable the drag and drop completely and code drag and drop by yourself (you can add drag and drop to the title that you pass).
