thanks for your help. Sorry if i wasn’t clear, i’ll try to make a practical example:
if you here http://soccervideo.tk/add-listing/
there are two packages: if you click on the packages you will see a box on the left sidebar called “Listing Enhancements”. I want that box to disappear for only one of them. So i believed a line of css code on a specific package id will do. Is this correct?
