I recently upgraded to WP 1.5 and it is great. I run a local community-based website (http://www.airdrie.net) and I am trying to convert my html pages to php. All is OK except that I am having difficulty trying to get a format for my local business directory listings pages. What I am trying to do is have a sidebar with main categories and somehow (like an i-frame) drop in pages to the main content area for the list of entries (eg Accountants, Bakers, Doctors etc). I have already done this with html but can't seem to figure out a way to do it in php (well not without a lot of work anyway). Has anyone got any ideas? Thanks.
