Using Categories

Sertorial

I am trying to categorise my content library, but I find that sub categories are not included when I view  category.

For example, when I view the category "Props" I want to be able to see everything under that category, but I can't see anything in subcategories of it (e.g. Props > Weapons) without clicking on weapons and viewing them separately. Is there some way to make all items under a heading visible together?

Thanks

EDIT: Oh wait, sorry. It does work like that. I hadn't noticed there were several pages of more items off to the right! Duhh!
