In my experience, it doesn't work. As i wrote earlier, most Superfish functionality will work, but if you use something else than a UL as your submenu, even if it's just wrapping a UL in a DIV for styling purposes, then the animation effects won't work. Superfish won't find the element it's looking for when trying to apply an animation, and thus the animation will fail. But i may be mistaken. Are you able to make the animation effects work with the same code as the YUI example, without hacking the Superfish code? Say you want to animate the height and opacity of the submenu, and as per the YUI example your submenu is a DIV containing a DIV containing a UL. Does it work for you?
