New Tab Container
Using Jamroom
Its a new container to drop widgets into. If you think of the current boxes as containers, then a tab container is the same, but whatever you drop into them becomes a set of tabs.
So if you have 3 pieces of related content you can have the top one shown on a page with the other two as tabs that need to be clicked on.
You've probably seen similar stuff around the net. Here is a page that has a lot of tabs on it:
http://demo.jamroom.net/jrProJam/
You can see the sections:
STATS | FEEDS | ONLINE
Is one group of tabbed content.
Blogs "ALL | FEATURED | LATEST | EXCLUSIVE"
Is another example from the demo page. The tabs on that page are created via the template and skins, but TAB CONTAINERS allows a similar thing to be done with widgets.
There would be absolutely no point in putting 1 widget in a tab container. Need to put 2 or 3 to see it working.
