Dinamic pages from DB created in backend to be displayed in frontend

Ok guys. I have a question for you. Let's suppose you have a site with a backend(admin panel). In backend you can add pages (that can be displayed on menu, submenu, active or inactive on site, frontend). How do you build the frontend. I mean let's asume the ADMIN creates a page in the backend pannel named "About" and set it to active and also want that to be displayed in the menu (in frontend). Since CI needs a controller(About)EX: site.com/About to display the about section of the site, how do i do that, how do i browse through the database and automatically create the controllers i need ? Or how do you manage that problem ? Cheers !
