I'm getting ready to have my old Joomla site redeveloped with WordPress. Using the Ecwid shopping cart system. Ecwid doesn't yet have support for category descriptions, so what I'd like to do is use something like qTip to create tool tip descriptions when the visitor hovers over a product category. I want to have my product categories appear permanently in a left sidebar. I'm new to WordPress (not a coder) and trying to find the best way to display several categories of products.. Any suggestion?
