Question

This is the simple Jquery code:

$(document).ready(function() {
    var activeIndex = $('#bmenul > li.totalactive').index();

    $('#bluenzbarimg').css({
        'marginLeft': (180 * activeIndex) + 'px'
    }).show();

    $('#bmenul > li').not('.totalactive').hover(function() {
        var index = $(this).index();
        $('#bluenzbarimg').stop().animate({
            'marginLeft': (180 * index) + 'px'
        }, 400);
    }, function() {
        $('#bluenzbarimg').stop().animate({
            'marginLeft': (180 * activeIndex) + 'px'
        }, 400);
    });
});​

This is the fiddle with almost exactly the same code than the website (except some css) and here the website.

Answer 1

I am guessing because

$('.bs-docs-sidenav').affix({

does not have the affix method, and therefor the rest of your javascript fails to load..

Either, you are missing a javascript include, or you just need to remove that call!
