Is there a way to mod this to show Subcategories in Boxes instead of the Parent Category?
No, this will only work with top level categories at the moment (but the category box will show the related subcategories as it does by default).
Thanks still an awesome component. I am guessing to get that added functionality would need a more complete category view replacement?
Following—this would be fantastic with subcategories. I have 32 subcategories under an umbrella cat.
