I just released version 2.6 Beta of the jQuery Horizontal Accordion for all PRO customers.
This version is feature complete, but still needs some cleanup and optimization. 

The included example file, should give you a pretty good idea of what the plugin can do and how its done.

All current customers can take it for a spin. The download is available through your customer account.

The next BETA is scheduled for next week, which will have a minimized version included again.
