Categories and Sub-categories are VERY frustrating. Why doesn't WordPress have the built-in ability to show Categories and underneath show all the sub-categories in that category and be able to click on whatever sub-category you want.
On the website all categories including sub-categories are on the same level. I need to show CATEGORIES listed underneath SUB-CATEGORIES - is shows it that way in the dashboard. Why have you made things so difficult when it should be really quite simple. It's quite insane the way it currently works!
