Hi Yavor Dashev,
Thanks for the above code snippet its very useful but the problem is you have created an html div that is dragging into smart docking tag. But what I need is to  drag from smart docking layout tag and drop also into smart docking layout tag. Something like,
<smart-docking-layout id=”dockingLayout2″ ondrop=”drop_handler(event);” ondragover=”dragover_handler(event);”></smart-docking-layout>
<smart-docking-layout id=”drag1″ draggable=”true” ondrag=”drag_handler(event);” ondragstart=”dragstart_handler(event);”>Lorem, ipsum dolor sit amet consectetur </smart-docking-layout>
But its not working for me.
I am looking forward to have any suggestion from you.
