Question

I am using Bootstrap v3.

I have the navbar classes in place so that when I have my screen mobile-size the navigation collapses and the little grid-like toggle button

Answer 1

Wanted to save time but it wasn't perfect. I got some issues with latest bootstrap, there is some unnecessary code and has a overflow problem in the drop-down menu. This code was the best solution for me:

.navbar-header {
    float: none;
}
.navbar-toggle {
    display: block;
}
.navbar-collapse.collapse {
    display: none!important;
}
.navbar-collapse.collapse.in {
    display: block!important;
}
.navbar-nav {
    float: none!important;
}
.navbar-nav>li {
    float: none;
}
