Кнопка показать еще в модуле "Техникс.Товары в блоках"

как правильно реализовать кнопку "показать еще" ? Сайт на opencart 3.x с шаблоном "Техникс". У меня получилось сделать кнопку через подсчет блоков и display:none, это работает, но столкнулся с проблемой. Товары выгружаются сразу все, получается подсчет ведется и в соседних категориях. Как мне это обойти ?

$(document).ready(function () {
   size_li = $(".col-6.col-lg-4").size();
x=3;
$('.col-6.col-lg-4:lt('+x+')').show();
$('#loadMore').click(function () {
    x= (x+5 <= size_li) ? x+5 : size_li;
    $('.col-6.col-lg-4:lt('+x+')').show();
     $('#showLess').show();
    if(x == size_li){
        $('#loadMore').hide();
    }
});
$('#showLess').click(function () {
    x=(x-5<0) ? 3 : x-5;
    $('.col-6.col-lg-4').not(':lt('+x+')').hide();
    $('#loadMore').show();
     $('#showLess').show();
    if(x == 3){
        $('#showLess').hide();
    }
});});
