Question

In my jstree I have a Root node which is the parent node of all. I have used dnd plugin. I want to allow drag and drop anywhere in the tree but only inside the root i.e. not before or after the Root.

- [Root]
   - Node 1
      - Node 1.1
      - Node 1.2
   + Node 2
   - Node 3
      + Node 3.1

After checking with forums I found that drag_check event is for foreign nodes only and not for any node within the tree. To validate for same tree node we need to use crrm -> check_move event. That is where I need help. I want to return false if the node is dropped before or after [Root].

Here is the fiddle to start – http://jsfiddle.net/juyMR/23/

You are very close, you just need a else statement to return true

 "crrm" : {
        "move" : {
            "check_move" : function (data) {
               // alert(data.r.attr("id"));
                if(data.r.attr("id") == "999") {
                    return false;
                }
                else {
                    return true;
                }
            }
        }
    },
