To understand what I am trying to do, take a look at my current website: http://www.coldclimategardening.com/oldindex.html
If you look on the sidebar, you can see I have 3 main categories of links: Cold Climate Gardening (ccg), Cottage Gardening (ctg), and Upstate NY (ny). Each of these is further divided into subcategories of information, gardens, merchants, forums, magazines, and books. If I’m understanding this correctly, it looks like I can assign categories such as ccg-info, ccg-gardens, ctg-info, ctg-gardens, etc., and use the template tag get_linksbyname to show the link name, description or notes (would one be preferable to the other?), and rss feed if available.
What I’m not clear on is how to structure the Pages. Is it possible to have a ccg template that would generate child Pages for each of the subcategories? If it’s possible, is it desirable, assuming I want to create a menu in the sidebar that shows the subcategories? If each child needs its own Page, does each child also need its own unique template, or can I create a generic template that will serve for all the child Pages? And once I create these Pages, where do I put them? Do they go with the other files in my current theme, or would WordPress look for them somewhere else?
