 spfDropDowns v.1 by @alirobe - gist: 1312059
 To use this, just structure your top-menu bar links by using a leading '-- '  
 to denote submenu items, e.g.

 Menu Item
 -- Submenu Item
 Menu Item
 -- Submenu Item
 -- Submenu Item

... make sure jQuery is referenced in your Master Page, before this file.

Trying to get this to work on a Foundation 2010 site. Do you know if anything has changed that would stop it working?

Ahh, I had the dashes wrong. It has to be -- dash, dash, space. Now it's working.
