Bootstrap, remove responsive from navbar

Answer 1

It can be done. Not too complicated actually.

I simply downloaded the Bootstrap 3 source code and scanned through their CSS file. They have @media queries for different screen sizes (as you already know). I simply copied all the CSS rules they use for @media (min-width: 768px) and put them in a new rule: @media (max-width: 768px)

Here it is so you can use it as it is:

CSS:

@media (max-width: 768px) {
    .navbar-header {
        float: left;
    }

    .navbar {
        border-radius: 4px;
        min-width: 400px;
    }

    .nav-tabs-justified > li > a {
        border-bottom: 1px solid #ffffd;
        border-radius: 4px 4px 0 0;
    }
    .nav-tabs-justified > .active > a,
    .nav-tabs-justified > .active > a:hover,
    .nav-tabs-justified > .active > a:focus {
        border-bottom-color: #fff;
    }

    .nav-justified > li {
        display: table-cell;
        width: 1%;
    }
    .nav-justified > li > a {
        margin-bottom: 0;
    }

    .nav-tabs.nav-justified > li > a {
        border-bottom: 1px solid #ffffd;
        border-radius: 4px 4px 0 0;
    }
    .nav-tabs.nav-justified > .active > a,
    .nav-tabs.nav-justified > .active > a:hover,
    .nav-tabs.nav-justified > .active > a:focus {
        border-bottom-color: #fff;
    }

    .nav-tabs.nav-justified > li {
        display: table-cell;
        width: 1%;
    }
    .nav-tabs.nav-justified > li > a {
        margin-bottom: 0;
    }

    .navbar-right .dropdown-menu {
        right: 0;
        left: auto;
    }
    .navbar-right .dropdown-menu-left {
        right: auto;
        left: 0;
    }
    .container {
        min-width: 400px;
    }

    .navbar-collapse {
        width: auto;
        border-top: 0;
        box-shadow: none;
    }
    .navbar-collapse.collapse {
        display: block !important;
        height: auto !important;
        padding-bottom: 0;
        overflow: visible !important;
    }
    .navbar-collapse.in {
        overflow-y: visible;
    }
    .navbar-fixed-top .navbar-collapse,
    .navbar-static-top .navbar-collapse,
    .navbar-fixed-bottom .navbar-collapse {
        padding-right: 0;
        padding-left: 0;
    }

    .container > .navbar-header,
    .container-fluid > .navbar-header,
    .container > .navbar-collapse,
    .container-fluid > .navbar-collapse {
        margin-right: 0;
        margin-left: 0;
    }

    .navbar-static-top {
        border-radius: 0;
    }

    .navbar-fixed-top,
    .navbar-fixed-bottom {
        border-radius: 0;
    }

    .navbar-toggle {
        display: none;
    }

    .navbar-nav {
        float: left;
        margin: 0;
    }
    .navbar-nav > li {
        float: left;
    }
    .navbar-nav > li > a {
        padding-top: 15px;
        padding-bottom: 15px;
    }
    .navbar-nav.navbar-right:last-child {
        margin-right: -15px;
    }

    .navbar-left {
        float: left !important;
    }
    .navbar-right {
        float: right !important;
    }

    .navbar-form .form-group {
        display: inline-block;
        margin-bottom: 0;
        vertical-align: middle;
    }
    .navbar-form .form-control {
        display: inline-block;
        width: auto;
        vertical-align: middle;
    }
    .navbar-form .control-label {
        margin-bottom: 0;
        vertical-align: middle;
    }
    .navbar-form .radio,
    .navbar-form .checkbox {
        display: inline-block;
        padding-left: 0;
        margin-top: 0;
        margin-bottom: 0;
        vertical-align: middle;
    }
    .navbar-form .radio input[type="radio"],
    .navbar-form .checkbox input[type="checkbox"] {
        float: none;
        margin-left: 0;
    }
    .navbar-form .has-feedback .form-control-feedback {
        top: 0;
    }

    .navbar-form {
        width: auto;
        padding-top: 0;
        padding-bottom: 0;
        margin-right: 0;
        margin-left: 0;
        border: 0;
        -webkit-box-shadow: none;
                box-shadow: none;
    }
    .navbar-form.navbar-right:last-child {
        margin-right: -15px;
    }

    .navbar-text {
        float: left;
        margin-right: 15px;
        margin-left: 15px;
    }
    .navbar-text.navbar-right:last-child {
        margin-right: 0;
    } 
}

Note that I commented out the .container rules so it won't have a fixed size anymore. Here's a copy of your fiddle with the new CSS: http://jsfiddle.net/Fraximus/5KAXf/1/

Let me know if it works.
