Help with Suckerfish Drop Down

i trying to use jquery to animate a sucker fish menu. It’s all working okay functionally, there is just one aesthetic glitch. Right after the menu drops down, it suddenly expands to the full width which is not what i want. I was hoping to have it come down already the full size. I’m a bit over my head with what’s going on with the jquery. Seems it should work this way … an yet …

Any idea how to make the full menu scroll?
