Get a tree node and call 'enable' and 'disable' methods provided in draggable to determine if the node can be draggable.

Code:

var node = $('#tt').tree('find', 12);  //find a node
$(node.target).draggable('disable');
$(node.target).draggable('enable');

Hey... do you have any solution to restrict any node to move away from its parent... and also restrict node to go into any node... in drag drop feature in tree... plz help ASAP....

The 'onDragOver' event is available from http://www.jeasyui.com/easyui/plugins/jquery.tree.js. Some codes looks like this:

Code:

$('#tt').tree({
	dnd: true,
	onDragOver: function(target, source){
		var cc = $(this).tree('getChildren',target);
		for(var i=0; i<cc.length; i++){
			if (cc[i].target == source.target){return false} // return false to deny drop, restrict the node to move away from it parent
		}
	}
});
