Since we have different types of clients, our "home page" will be "who are you?" and then once they select the type of client they are it'll send them to their homepage with its own menu. 

So three different clients with 3 different menus and the initial page wouldn't have a menu. 

How can i go about doing this? How can I hide a menu from a page but also have 3 different menus and delegate them to certain pages?
