[jQuery] Avoiding recreation of the wheel with horizontal drop-down menus

[jQuery] Avoiding recreation of the wheel with horizontal drop-down menus


Following LinkedIn's relatively recent site redesign, I feel compelled
to believe that the way they've approached their top navigation bar is
the correct way.
The text links work as normal links and the small arrows trigger the
drop-down navigation.
Does anyone know how to impliment this in jQuery? Has it already been
done?
Thanks
