Title: Disallow Drag and Drop between the same tree
Post by: leela on July 23, 2014, 08:15:49 AM

Hi,

I have 2 trees, The user should be able to drag and drop the elements from the left tree to the right tree.
But disallow drag and drop between the left tree. Is there a way I can find , if both source and target belong to the same tree in any of the events (onDragOver, onBeforeDrop)

When user tries to drag something from my left tree with in left tree, I should be able to recognize it and prevent it.

Please advise.

Return false in the 'onDragEnter' event and the target node will not be dropped.

Code:

$('#leftTree').tree({
	onDragEnter:function(target, source){
		return false;
	}
})
