Answer 1

There are numerous things to change the collapse breakpoint in the css, you would need a VERY good handle on mobile first responsive design to do it OR use the LESS, but the fastest way is to visit:

http://getbootstrap.com/customize/

And enter the breakpoint that you want in the @grid-float-breakpoint field. The choices are the Media queries breakpoints listed @screen-sm-min is where it defaults, it used to default at the @screen-md-min (or thereabouts) in 2.x.

Also read the docs and use the examples as starting points. None of the implementations of the navbar are contained in column classes as those are used inside .rows and there's supposed to be .container directly inside the navbar.

Answer 2

For those who might need it, this is what I did.

@media only screen and (min-width: 500px) {
    .collapse {
        display: block;
    }

    .navbar-header {
        display: none;
    }
}

@media only screen and (max-width: 500px) {
     .collapse {
        display: none;
     }

     .navbar-header {
        display: block;
     }
}

So what I did was to hide the toggle mobile button and still display my menu on that specific width and vice-versa when the width is less than 500px.

Answer 3

If your using Less go to the variables. Less file and change the following variable from:

//** Point at which the navbar becomes uncollapsed.

@grid-float-breakpoint:     @screen-sm-min;

to:

@grid-float-breakpoint:     @screen-md;

That would make the collapsing nav work on portrait tablet size down.

Answer 4

For those looking in SASS,

Just ensure you have the override of the "$grid-float-breakpoint" before your bootstrap import.

$grid-float-breakpoint: 992px;

Is How I changed mine.
