How To Create Dynamic Menu In MVC 4.0?

In that link which you mentioned in the post, they are following code-first approach in EF it seems.

If you want to follow DB-first approach then create a table called Menu & MenuItem with the columns as mentioned in Menu & MenuItem models [classes]  in that post.

Or it can be simply,

MenuID MenuName      MenuLocation ParentID 
1        ParentItem1   NULL             0
2        ParentItem2   NULL             0
3        ParentItem3   NULL             0
11      SubMenuItem1NULL            1
12      SubMenuItem2NULL             1
21      SubMenuItem3NULL             2

Add fields which you want.....
