I develop a module which has 7 nodes and a menu have 7 submenu. What can i do to meet these following requirements :
1. There is a choice list which has a lot of choices which are specials code.
2. If i choose a code, it will affect the view of 7 tabs.
For example ,if i choose code "Apple" , it will present some information about "Apple" if i choose menu "What", .If i choose menu "Buy",it will list information of who buy it. So on.
3. All the unauthorized user can access it . ( I think this is affected by hook perm).

Please , give me an simple example if you can .
Thank you for your supporting.
