        var filter = $('#filter');

                        /* Stuff to do every *odd* time the element is clicked */
        $.ajax({
            url:filter.attr('action'),
            data:filter.serialize(), // form data
            type:filter.attr('method'), // POST
            beforeSend:function(xhr){
                filter.find('button').css('opacity', '1').text('Загрузка...'); 
                // changing the button label
            },
            success:function(data){
                filter.find('button').css('opacity', '0');; // changing the button label back
                if($(".checkbox:checked").length == 0) {
                                $('#response').empty(); 
                          } else {
                                $('#response').html(data); 

                                 };

                                 $(".usage-product-list li").each(function () {
                                        if ($(this).text() == 'Усиление иммунитета') {
                                            $(this).css('color', 'red');
                                        }
                                    });


                                }
                    });
        return false;
                    });
//end jquery ajax

    // load more toggle start
    $('.load-more').toggle(function() {
    $(this).html('Меньше параметров <i class="fas fa-angle-up"></i>');
    $('.row-wrap').slideDown('slow');
}, function() {
    $(this).html('Больше параметров <i class="fas fa-angle-down"></i>');
    $('.row-wrap').slideUp('slow');
});
    // load more toggle end


    $('#filter input[type="checkbox"]').click(function () {
            $(this).siblings('span').toggleClass('active');
        });
