Both of those are from modified code.

None of the default navtabs have dropdown menus - so you did this yourself with a modification or you wrote the code yourself. We can't really help with that without knowing your code. (and if it's from a modification, you need to post in that modification thread for help.)

I also cannot see any dropbox when I click on the Media tab. I also see no "Bop" thing on your site.

edit: Oh, I found the "Bop" thing. You'll need to post in the modification thread for help with that. Or, just use firebug to figure out what css is used and change it yourself.
