Of course! It seems a great idea. Thanks.

About the show hide of the buttons, I'm seeing here and there that, for accomplish something like this we could use only CSS or CSS+Javascript.

I more or less got the concept but there is something that bogus me:
I want to display the child elements when the parent is clicked. That's for sure.
But, I'd like also to display the child elements, when anyone navigates directly trough the URL. (for an external link for example)

ie.
www.mysite.com/c_category/categoryID/subcategoryID

How do you normally solve this, is order to allow access to hidden parts of the menu, not only when the user clicks, but also, when some URL is on the address bar?
On the server side, using CI libraries? Or more on the js side of things?


Thanks in advance,
