Defining specific content fields for a page

Hi,

I need to create a site for a client. It needs to be very easy and intuitive for the client to add content to the website. In order to make the process straightforward and easy, while also maintaining the clarity and integrity of the site's content, I would like to define certain content fields that can be filled out in order to create a new product page. My client is a wholesale distributor of fire safety products, so they will need to enter things such as Product Category Description, Manufacturers who carry the product, etc.. Does anyone know how to set up fields like this in websitebaker? I would also like for these fields to be the basis of some dynamic placement of content on pages (I'm not sure what the capabilities are for that in WB). I know how to do this in Drupal, but it's so different here. Any help would be appreciated. I can provide more details if necessary.

Thanks!
Johnna
