Disable Category Selection
I have several categories and sub-categories on my website.
I only want to make certain Ad Categories availble for people to post in.
Eg,
Category 1 - Buy
Category 2 - Sell
Category 3 - News
I want everybody to be able to post in Categories 1 and 2 however, I dont want anyone to be able to post in Category 3
Is this posible?
