Without looking for exact specifics yet, is it possible to extend the native DNN menu to read a list of categories and their related page targets from a user table of categories from a product catalog? ie, DNN menu would still use the default menu handling (is menu item? checkbox) for pages, but for one page, (say "products"), the menu has a sub menu of categories and sub categories, clicking on a category, would link to products/category.aspx. Is this possible? Is there a pre built option? Is there a better option for building?

Thanks for your input.
