I found the solution.

   $("#tree").jstree({
//...
      "crrm" : {
        "move" : {
          "check_move" : function (m) {
            return false;
          }
        }
      }
//...
      "plugins" : [ "crrm", "dnd" ]
    });

    "crrm" : {
            "move" : {
                "check_move" : function (m) {
                    if(m.cr.attr("id") == m.r.attr("id")){
                        return true;
                    }else{
                        return false;
                    }
                }
            }
    }
