I have had great success with the Stories module. However, there is one thing I would like to be able to do, and I don't know if it is possible.

I have a Main category ("Main 1"), and this has three 3 Sub categories (Sub 1, Sub 2, Sub 3), and there are articles under each of the three Sub categories. When I select Main 1 from the dropdown menu, none of the articles in the sub-categories show up, only articles directly under Main 1. Logically, shouldn't selecting Main 1 show all articles that fall under it's hierarchy, including articles in subcategories?

Is there a way to do this?
