Hello!
I have them working with Bootstrap 3.0.0 and 3.0.1, using the GetBootstrap.com styles. Works like a charm, except on mobile devices.
For mobile devices, I found I had to override the dropdown-backdrop style to position: static in order for the menu items to work on mobile devices (can read more here: http://stackoverflow.com/questions/13902734/bootstrap-cant-click-dropdown-child-menu-items-on-mobile-and-first-click-not).
HTH!
