Question

How can we have a Multiple site maps in Asp.Net MVC solution?

 

For example:

 

I have 3 modules in my Application let say Student, Employee, Teachers.

 

I have these 3 modules in the menu bar.

 

Now when i navigate to Student module i should see the student specific sitemap. Same for the others as well.

 

How can we achieve this functionality in ASP.Net MVC?
