There's a very common need of creating something like, let's say, a catalog of goods - a number of sections which has sub-sections which, in turn, has a number of goods or other items.

As I can see so far, I can create a tree-like structure of categories in one module and a list of goods in other module, and connect each item to  some sub-category. But it is pretty inconvenient. For example, it's impossible to open an arbitrary category's items list - you have to create a view for every specific category.

One can also create a tree of pages, but you cannot assign different field types to a page, which is also bad.

I hope I just doing something wrong and there is an easy way of doing that. Can anyone help?
