Frames or page in page…..

Hi all,

Not sure if this is a theme/ccs question or not but here goes.

I was wondering if I could put page in page on a WP site. I would like to use wordpress as my main site with posts and pages but would like to open a store page using zen/oscommerce/magento/…(Not sure yet) and I’d like this to open below the menu bar as if its part of WP and giving access to the menus so you can flick between the two and not notice the change. It should all look like one site.

Is this possible for a non code to achive. I am able to edit php files etc but not necessarily understand the fine details of the code so it needs be a faily trivial thing to do if I’m able to acomplish it.

My theme is zBench 1.3.4 by zwwooooo.
My site is http://www.robsbots.co.uk
(Excuse the current state of the site. It will improve.)

Thanks for any suggestions or pointers you can provide.

Rob
