Responsive design Menu with Repeater using asp.net and c#

Question

Hello All,

I am working on "respondive design" based template whereby I retrieve the Menus (e.g. Home, About Us, Contact Us and Services) from the Database (Sql Server 2012). It is because if a specific Menu is hidden, then I should not show it as part of the Menu bar. I have now hit a problem when trying to see these Menus in Mobile and Tablet. It appears but as if you see on a PC/Laptop, i.e. all Menus displayed in one bar.

I understand normally in Mobile and Tablet the Navigation tag is used to display the Menus within a single NavImage (i.e. drop-down format). But in my case, I think, due to the use of repeators the NavImage is not working. The error I receive is NavImage not supported

I am hoping there is a way to show the Menus in Mobile and Tablet in the drop-down format even if it comes from a DB. Please advise.
