css

Recently worked on a site that used a "megamenu". These are drop down menus on steroids, using css to hide/show "panels" of links appropriate the parent item. The menu worked fine, however when accessibility testing using the "tab" key (no mouse) I discovered that on IE8, IE9 and IE10, the tab key would not "find" the child links for the top level items.

Repeated "tab" key usage caused progress to loop on the first 2 parent items.
