// Add active class to active navigation link
$(document).ready(function () {
    $('ul.nav.navbar-nav').find('a[href="' + location.pathname + '"]')

});

Change Navbar breakpoint (mobile vs normal)

max-width is the breakpoint

@media (max-width: 1200px) {
    .navbar-header {
        float: none;
    }
    .navbar-left,.navbar-right {
        float: none !important;
    }
    .navbar-toggle {
        display: block;
    }
    .navbar-collapse {
        border-top: 1px solid transparent;
        box-shadow: inset 0 1px 0 rgba(255,255,255,0.1);
    }
    .navbar-fixed-top {
        top: 0;
        border-width: 0 0 1px;
    }
    .navbar-collapse.collapse {
        display: none!important;
    }
    .navbar-nav {
        float: none!important;
        margin-top: 7.5px;
    }
    .navbar-nav>li {
        float: none;
    }
    .navbar-nav>li>a {
        padding-top: 10px;
        padding-bottom: 10px;
    }
    .collapse.in{
        display:block !important;
    }
   .navbar-nav .open .dropdown-menu {
       position: static;
       float: none;
       width: auto;
       margin-top: 0;
       background-color: transparent;
       border: 0;
       -webkit-box-shadow: none;
       box-shadow: none;
    }
}

Close collapsed navbar when clicking outside of the navbar

jQuery('body').bind('click', function(e) {
    if(jQuery(e.target).closest('#navbar').length == 0) {
        // click happened outside of .navbar, so hide
        var opened = jQuery('.navbar-collapse').hasClass('collapse in');
        if ( opened === true ) {
            jQuery('#navbar2 .navbar-collapse').collapse('hide');
        }
    }
});
