Move item on TreeView

Hi,

I am trying to modify tree in TreeView (on client side).
Since I would like to use standard PC and touch device, I can’t enable drag and drop.
So I need to do modifications with a toolbar (up, down, change level, …)

Is there a function to move item with API (moveItem of Tree does not exist for Treeview).

Thanks

Unfortunately there is no API to move the item in the treeview.
