Take a block area and split it into multiple columns. New columns can have custom names and automatically divide the space into equal parts.
There are also templates for using tables instead of columns, tabs, and an accordion

KNOWN LIMITATIONS:
Currently this block doesn't work with the Scrapbook in concrete pre 5.5 or Stacks/Clipboard in concrete 5.5 and over.

STATUS: BLACK
This works much of the time, but it's not guaranteed to work with everything else in the marketplace! Purchase and use with care.  **

NEW IN VERSION 2.1
Fully compatible with 5.5.0 and 5.5.1

NEW IN VERSION 2.0.10
Fully compatible with 5.4.2.2
Improved JSON validation in Tabs and Accordion templates. Invalid JSON options will be silently ignored instead of giving unexpected results.

NEW IN VERSION 2.0.7
Updated JqueryUI for 5.4.1 compatibility.
PLEASE NOTE: If you have created custom jqueryUI themes for your area splitter, you'll have to update your themes and move them to the appropiate location.

NEW IN VERSION 2.0.3
Fully implemented versioning support! Yay!
NOTE: This version requires c5 5.3.3.1

NEW IN VERSION 2.0.2
You can now code templates that create sub areas on the fly. Much like how page types work inside the theme. This should give developers huge flexibility to create complex templates with sub-areas. I've included a sample template in the code to show you how this is done.
