多列滑块在一页中使用引导程序4，带有多个滑块

Question

我创建了一个页面，其中我有三个bootstrap 4轮播，每个都有不同的id名称，但我对第三个轮播有问题，因为我希望它有多个显示或每个幻灯片显示多个列*（这是我的产品页面，我显示产品类别）*我试图添加脚本，但它也影响第1和第2轮播

    $('#category_carousel').carousel({
      interval: 3000
    })
    $('.carousel .carousel-item').each(function() {
      var next = $(this).next();
      if (!next.length) {
        next = $(this).siblings(':first');
      }
      next.children(':first-child').clone().appendTo($(this));
      if (next.next().length > 0) {
        next.next().children(':first-child').clone().appendTo($(this));
      } else {
        $(this).siblings(':first').children(':first-child').clone().appendTo($(this));
      }
    });
    
    
    $('.carousel').carousel({
      interval: 4000
    })

.carousel-item>div {
  float: left;
}

.carousel-by-item [class*="cloneditem-"] {
  display: none;
}

.carousel-item .img-fluid {
  width: 100%;
}

.carousel-item>div {
  color: black;
}

.carousel-item a {
  display: block;
  width: 100%;
}

category_carousel ID是我想要多重显示的第三个旋转木马，第一个和第二个只是普通的旋转木马

是否有任何方法或程序可以将脚本添加到html中的特定ID或CLASS？
