Treetable drag-n-drop grouping

Webix JS
1

Hi,

i am trying to add a small functionality to the Treetable, i.e. i would like to be able to drag-n-drop siblingA upon siblingB and this should transform siblingB to a parent (with a plus-sign next to it), where siblingA becomes a child to it.

I couldn’t find an easy way to do this till now. Could you please show me the right way?

Thanks a lot.

You can enable the desired behavior, by using code like next

tree.attachEvent("onBeforeDrop", function(context){
      context.parent = context.target;	        //drop as child
      context.index = -1; 				//as last child
});

Unfortunately the case when you are transformin leaf item to the branch have a problem ( the above example doesn’t work very well after new branch creating )

To have the correct behavior you need to update the lib as well ( the same fix will be included in the next build )
