The menu should work as it would on any other servers, just check the tooltips for a cheat before you enable it to see if it is CAC detected or not, if you're not sure if the server has CAC, open up your console and type in "ulx cac" and hit enter, if you get the output message: "Invalid command entered. If you need help, please type "ulx help" in your console." the server most likely doesn't have CAC, though clever peeps can probably remove the ulx command from itsince I don't think it is a vital part of it.
