I've got a CSS dropdown menu on my website (http://www.averybiomedical.com) that is based off of the suckerfish model. I would like to increase the width of the dropdown menu to be greater than that of the heading. I've done that part with some additional CLASS statements. The problem is the result looks like this:

|_________|_____
|_______________|
|_______________|
|_______________|

I would like the dropdown to be centered under the heading, not left aligned, like this:

___|_________|___
|_______________|
|_______________|
|_______________|

I cannot find a suckerfish example that is not left aligned, and can't figure out what variables I need to set to get this result.

Any help would be greatly appreciated.
