Hi guys,

I learn how to make a menu bootstrap + c# + asp.net + sql server in this article ( http://www.aspsnippets.com/Articles/Bootstrap-Responsive-ASPNet-Menu-control-for-Mobile-Phone-Tablet-and-Desktop-display.aspx ) , but , i can't add more one Parent menu.

Example in article:

Menu 1 Menu 2 Menu 2.1 Menu 2.2 Menu 3 Menu 4

My problem is:

Example in article:

Menu 1 Menu 2 Menu 2.1 Menu 2.2 Menu 3 (show as menu) Menu 3.1 (not show) Menu 3.2 (not show) Menu 4 Menu 5

I don't have ideia about this problem
