frames render size

[iwuser]

Trying to fit a frame into a flex template page design, I cannot see how to prevent the frame from rendering its size. As a result, it shows smaller than the size of div above, using design-time width.

"Align" does nothing to help.

Is it possible to stop frames from rendering their sizes?

Or if it's not possible, what's the best practice for a multi-form design with a Template (i.e.: without using Frames)?

I can have multiple forms using the same template, but on change the screen refreshes and I have to maintain shared menu state. I was hoping to have a single Form, which would basically handle the menu and switch frames, but that isn't working the way I wanted it to.

Or can forms be rendered inside a Region on the main form instead? Or should I use Tabs instead (would probably look too busy)? Or create all contents dynamically, without resorting to any frames (probably too much pain to develop)?
