It's posting profile to index.php you would need to use CodeIgniter input->get() to retrive it.

The menu is most likly use javascript. If you want to learn it goto jQuery.com

I converted this menu sytem over so that I could use it in CodeIgniter and belive me it was not that easy.

Easy Menu
I had to change all the jQuery url's etc. rewrite all the code to use MVC.

One of my senior developer told me that the developer of this theme has does something due to that this type of url are generated and recognized by the custom menu url .
