Edit form in a split screen

[Volker Trapp]

I have a table with a lot of fields. I can create a edit form with tabs inside to goup the fields. when I open the view form it fills the complete area. I can open the edit form by double click or by clicking the edit button.

I would like to have the sreen splitted horizontally. In the upper half I would like to see the viewform ( table view) and in the lower half I would like to see the edit form (field view )

How can this be done ?
