Create More Widget Holders Like Active Widgets and Inactive Widgets

enter image description here

Probably isn’t considered “best practices” but it gets the job done.

Here’s what I did: In my wp-admin/widgets.php,

After these lines,

// register the inactive_widgets area as sidebar
register_sidebar(array(
    'name' => __('Inactive Widgets'),
    'id' => 'wp_inactive_widgets',
    'class' => 'inactive-sidebar',
    'description' => __( 'Drag widgets here to remove them from the sidebar but keep their settings.' ),
    'before_widget' => '',
    'after_widget' => '',
    'before_title' => '',
    'after_title' => '',
));

add this

register_sidebar(array(
    'name' => __('Media Widgets'),
    'id' => 'wp_inactive_widgets2',
    'class' => 'inactive-sidebars2',
    'description' => __( 'Drag widgets here to remove them from the sidebar but keep        their settings.' ),
    'before_widget' => '',
    'after_widget' => '',
    'before_title' => '',
    'after_title' => '',
));

When you add your widgets to the new holder, they’ll display all the way across like in my pic. Perhaps because no styling was done to this new holder. Anyway this is working for me, I logged out and back in and my widgets are still there.

As always, when changing themes, your “Media Widgets” will be moved to the “Inactive” holder if the new theme doesnt have the same sidebar setup as the previous one.
