DhtmlxFolder drag and Drop

I have 10 folder and 100 file out side the folders and I want to drag and drop the last file at end into the first folder using dhtmlx folder control. As I was checking dhtmlx.com/docs/products/dhtmlxF … -drop.html and I was not able to Drag-drop Eula file into ‘classes Directory’ which was on the top.
When I am trying to drag the file the vertical bar is not moving as I am moving the item. Please let me know how I can do this.



I’ve attached the latest folders version. Try to use it. Locally the problem doesn’t occur with it
