Using of draggable, droppable & sortable at once.

Hi Everyone,

I'm trying to develop a functionality so that a user can drag and drop form fields from once side to another side having multiple sections with subsection.
After that he can drag and drop the that section or subsection or any field in any section or sub section of the existing.

I have start making it and got stuck in thing that duplicating the sections and dragging into other.
