How Do I show more subcategories?
 

Currently you can show unlimited (?) categories, but none of the subcategories are shown by default (only the parents are shown).

Is there a way to let the subcategories to be shown in the lists of categories?

Currently, no. If the cateogry does not have a parent though then it will list that category's sub-categories below it.
