drag and drop treetable not open first level

Hello , I use drag and drop between two treetables.
When I move an entry to other treetable, if first level was close the hover of drag and drop open the first level before I finish the action.
How it possible to keep state of treetable destination (not opened first level) ?

Thanks

Hello,

You can use onBeforeOpen event to prevent branch opening in the treetable.
