Superfish in the menu enhancement Javascript of choice. For those already using jQuery as their Javascript library, Superfish is an easy choice. Superfish is of sufficient use to convert some Web site developers who are not using jQuery.
Download Superfish from users.tpg.com.au/j_birch/plugins/superfish.
Superfish is used in the Aardvark theme used on this site. The menu bar across the top of the page was created in Aardvark from CSS based menus used in previous themes. Superfish adds a slight stability that makes mousing over the menus a delight.
The menus were developed years ago using HTML then updated to CSS as soon as CSS had the right facilities. CSS menus react too quickly and you often miss the right menu entry because the CSS menus flick away before you select the item you want. Superfish introduces a delay before the menu drop down elements disappear. With Superfish you get time to select the right entry.
Fallback
What happens when Javascript is turned off? You get the CSS menus you had working before you added Superfish.
jQuery
Superfish uses jQuery and jQuery is already supplied with your content management system, assuming you use a good CMS. Drupal is the best example of a good modern CMS.
Drupal theme
Some Drupal themes are supplied with Superfish style menus built in. Aardvark is supplied with the original Superfish files untouched.
Drupal module
There is a Drupal add-on module, drupal.org/project/superfish, to add Superfish to existing menus if you use an older theme.
