TIWCGJQTreeViewDNDPlugin.OpenTimeout Property
The number of milliseconds to wait before opening a hovered if it has children (while dragging). This means that the user has to stop over the node for half a second in order to trigger the open operation. Keep in mind that a low value in combination with async data could mean a lot of unneeded traffic, so 500 is quite reasonable.
