Creates one or more tabbed dynamic sidebars for your sidebar
Unzip the plugin into the plugins directory and activate. In wp_admin go to Widgets, under the presentation tab. Here you can select the number of tabbed sidebars that you want using the panel at the bottom. You can them use either the Fun with Sidebars Widget (by adding each Tabbed Sidebar widget into your main sidebar) or the template tag -
<?php the_tabbed_sidebar( Tabbed Sidebar number ); ?>
You can then add widgets to each Tabbed Sidebar on the same page.
