This plugin adds a magic sidebar which you can fill with widgets and a widget that displays the magic sidebar’s contents as tabs. Sounds more complicated than it really is!

Tabbed Sidebar Widgets

Pack multiple sidebar widgets into one convenient tabbed container.

A plugin that allows you to create widget areas that can be turned into tabs or 
accordion using widgets or shortcodes.
Use the settings page to define as many widgets areas as you want then use the 
“Ultimate Tabbed Widgets” widget to show those areas as a set of tabs or an 
accordion in your sidebars.
You can also use the <code>[utw widgets="name of area" template="tabs|accordion"]</code> 
shortcode to show a set of tabs or an accordion inside a post or a page.

Ultimate Tabbed Widgets

I needed to have multiple instances of a tabbed widget. I was using a plugin called "Tabber Tabs Widget" which worked, but it only had one widget area.
This plugin lets you add multiple, then assign them as needed to existing widget areas. So you can have multiple sets of tabbed widgets assigned to multiple sidebars.
The only think it doesn't have is the ability to have multiple widgets on each tab, but I didn't need that (or expect that).



Works great!
