I have an MVC4 app in which I'm trying to change the layout. It's my understanding that in Bootstrap, a responsive app, when shrunk to a certain size, will replace the menu with a button that can call up the menu as a dropdown.
My goal in changing the layout is to replace the horizontal navbar at the top with a vertical menu along the left side. To this end I have replaced the navbar with a main-nav. (Trying to duplicate the menu setup of another app we have.) I am aware that
the 'navbar' is solely a horizontal object and other techniques need to be used to create a vertical menu.
So far what I see appears to be 'responsive' but no dropdown button appears to call up the current menu.
What conditions do you have to meet to insure the button appears?
