        $('select').material_select();
        $('select').change(function(){
            var newValuesArr = [],
                select = $(this),
                ul = select.prev();
            ul.children('li').toArray().forEach(function (li, i) {
                if ($(li).hasClass('active')) {
                    newValuesArr.push(select.children('option').toArray()[i].value);
                }
            });
            //select.val(newValuesArr);
            $(select).data('var', newValuesArr)
        });
