Drop down menus

[Green Bandits]

Okay so I am new to these types of forums and am trying to get used to some of the features. I am noticing on my site, theres different drop down menus for Forums, Calendar, Online Users, Profile, Admin CP, Mod CP, etc. Is there any way for me to get rid of the drop downs and just have these things display across the top of the forums? Also if so how would I be able to decide which to display and which to completely hide or get rid of?

That's all controllable via ACP > System > Site Features > Menu Manager.
