<script>
    $(document).ready(function(){
        var init = new Init();
        $(document).off('click.bs.dropdown.data-api');
        init.dropdownitem();
    });
</script>

Init.prototype.dropdownitem = function () {
    $('li.dropdown').mouseover(function() {
        $(this).addClass('open');
    }).mouseout(function() {
        $(this).removeClass('open');
    });
}
