Superfish is a jQuery plugin for progressive enhancement of suckerfish- style HTML/CSS drop-down menus. It can be found at http://users.tpg.com.au/j_birch/plugins/superfish/
The original Superfish plugin used jQuery's hide() method, which sets an inline css attribute of display: none on the hidden menus. This has the unintended effect of making screen readers skip over the submenus. Since screen readers cannot easily trigger the hover event, this effectively blocks them from accessing any of the sub menu items. This modification changes the css technique used to hide the menus visually while leaving them available for screen readers. You can grab the updated code here http://jsbin.com/useku (Apologies if this is the wrong place for this posting - the author of the original Superfish plugin mentioned this list as the place for support for the plugin. Thanks!) Jason Denizac
