Placeholder problem

[Nat]

Hello,

a question to John or some other specialist: I´ve created in XWB a members section site, where i want to put active content. Unfortunately things do not work so well. As you can see the design has a placeholder for an html table, which works fine (you can´t see the table because the frames are set to invisible). Here the actice content has to appear. It does, but as the page has a fixed size it doesn´t fit vertically and horizontally to the content (you can see the attached jpg). How can i resolve the problem? Using the tweak for dynamic pages? Well, i don´t know how to do that for my design. Would be grateful for any help.
