BogoTabs is [yet] another tabbed interface plugin for jQuery.
Aside from the conventional tabs it offers the ability to create “hidden tabs”. That is, tabs which have no associated activation button, but can be displayed via programmatically activating them. This allows one to create their own custom buttons for tabs, e.g. on the sides or bottom of the tabbed panel.
It is not as complete/nice as “Klaus’ Tabs” (i.e. “the” jQuery tabs), but it works and is easy to work with. Unlike Klaus’ tabs, it does not “degrade gracefully” when used in a non-JS environment (but in fact no tabs plugin truly degrades gracefully because the tabs themselves are left laying around in completely unintended places when JS is not available).
