Facing problem in implementing draggable at column layout

[a.premkumar]

I am trying to create a sample similar to the Portal example. Like Portal example, my example also has a Main Panel and inner panels (Child panels). Main panel has column layout. I am struggling with rearrangement of inner panels, when they are dragged. I have to move the panels down when some other panel is dragged and dropped in their position. So it would be helpful if anyone points me to the right direction.

So the columns are your inner panels or you have inner panels within the column containers?

I have panels within the columns.

I have found an alternative Mitchell, I have adopted and modified the code of Portal to my need. Anyway thanks for your concern and time.
