jQuery Superfish Dropdown Menu Plugin
Our favourite aquatic superhero returns from his sojourn across the galaxy infused with astonishing, hitherto unseen new powers. In his modern incarnation (wearing a rather spiffy cape) Superfish is dedicated to keeping dropdown/flyout menus accessible across browsers great and small, in addition to adding support for newer touch devices (running Android, iOS, Windows, etc). All this and a pretty face.
Documentation and Demos
Please use the existing Superfish documentation where you will find full explanations of the customisable features and plenty of examples to get you started.
Superfish menus have been in use since the dawn of time (well, around 8 years or so) and many are the places where you can find help with your Superfish implementations. Check out the support options.
