MVC -DropDownList - Categories - SubCategories

Answer 1

Just load the data in the controller and structure it as you see fit ... then all you need to do is pass the list to the dropdown html helper and it doesn't have to know anything about the data's structure.

If you embrace the separation of concerns that is afforded to you when you fully buy into the MVC pattern, this sort of thing answers itself :-P

Answer 2

Hmm I don't understand? As you can see the categories table has style inside the dropdown. Should I store everything inside a IList? and then inside the controller. should I store inside a Viewdata?

can you give example?
