Bootstrap Carousel：滑动带Carousel的缩略图

Question

I am trying to use image thumbnail instead of orderd list for carousel indicators. I followed some instructions here and created this in jsfiddle

It works fine, but as you can see the thumbnails has a scroll bar to fit them all. How can I slide/move thumbnails as the carousel slides?

Here is the CSS that creates the thumbnail:

#carousel-custom .carousel-indicators {
  margin: 10px 0 0;
  overflow: auto;
  position: static;
  text-align: left;
  white-space: nowrap;
  width: 100%;
}

#carousel-custom .carousel-indicators li {
  background-color: transparent;
  -webkit-border-radius: 0;
  border-radius: 0;
  display: inline-block;
  height: auto;
  margin: 0 !important;
  width: auto;
}

#carousel-custom .carousel-indicators li img {
  display: block;
  opacity: 0.5;
}

#carousel-custom .carousel-indicators li.active img {
  opacity: 1;
}

#carousel-custom .carousel-indicators li:hover img {
  opacity: 0.75;
}

#carousel-custom .carousel-outer {
  position: relative;
}

Thank you,

 $(document).ready(function() { $('#myCarousel').carousel({ interval: 10000 }) $('#myCarousel').on('slid.bs.carousel', function() { //alert("slid"); }); }); 

 .carousel-control { padding-top:10%; width:5%; }
