Working with tree/treetable and I want to modify the default behaviour of dnd. At this moment is doesnt seem possible to drag a sibling to its fellow sibling and make that a parent by dropping it on it. It only works if the item already is a parent, not just an item (you should even consider this feature).
In any case, Im therefore trying to modify the onBeforeDrop event, which is in the API and in this article: http://docs.webix.com/datatree__dnd_support.html#advanced but I cant seem to fire the event. Same for onAfterDrop.
See my example also:

Apart from this, you might notice that if you start dragging drag fast enough, the onBeforeSelect also doesnt always fire (in Chrome and FF at least). I also noticed that when you drag an item downward fast enough, it sometimes gets lost totally (just drag it down really quickly a couple of centimeters and let go of the right mouse button very fast when/before stopping moving, literally try to ‘throw away’ the item).
