Bootstrap carousel multiple frames at once

Bootstrap 5 (Update 2021)

While the carousel is mostly the same in Bootstrap 5, the concept of left and right have changed to start and end since Bootstrap now has RTL support. Therefore the left/right classes have changed. Here’s an example of the multi-item CSS for 4 items (25% width columns)…

@media (min-width: 768px) {
    
    .carousel-inner .carousel-item-end.active,
    .carousel-inner .carousel-item-next {
      transform: translateX(25%);
    }
    
    .carousel-inner .carousel-item-start.active, 
    .carousel-inner .carousel-item-prev {
      transform: translateX(-25%);
    }
}

.carousel-inner .carousel-item-end,
.carousel-inner .carousel-item-start { 
  transform: translateX(0);
}

Since jQuery is no longer required, we use vanilla JS to clone the slides into the carousel-item divs..

let items = document.querySelectorAll('.carousel .carousel-item')

items.forEach((el) => {
    // number of slides per carousel-item
    const minPerSlide = 4
    let next = el.nextElementSibling
    for (var i=1; i<minPerSlide; i++) {
        if (!next) {
            // wrap carousel by using first child
            next = items[0]
        }
        let cloneChild = next.cloneNode(true)
        el.appendChild(cloneChild.children[0])
        next = next.nextElementSibling
    }
})

Bootstrap 4 (Update 2019)

The carousel has changed in 4.x, and the multi-slide animation transitions can be overridden like this…

.carousel-inner .carousel-item-right.active,
.carousel-inner .carousel-item-next {
  transform: translateX(33.33%);
}

.carousel-inner .carousel-item-left.active, 
.carousel-inner .carousel-item-prev {
  transform: translateX(-33.33%)
}
  
.carousel-inner .carousel-item-right,
.carousel-inner .carousel-item-left{ 
  transform: translateX(0);
}

Bootstrap 4.1.0 (advance all 4 at once)
Bootstrap 4.3.1 responsive (show multiple, advance 1)new

Another option is a responsive carousel that only shows and advances 1 slide on smaller screens, but shows multiple slides are larger screens. Instead of cloning the slides like the previous example, this one adjusts the CSS and use jQuery only to move the extra slides to allow for continuous cycling (wrap around):

Bootstrap 3

Here is a 3.x example on Bootply: http://bootply.com/89193

You need to put an entire row of images in the item active. Here is another version that doesn’t stack the images at smaller screen widths: http://bootply.com/92514

EDIT Alternative approach to advance one slide at a time:

Use jQuery to clone the next items..

$('.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));
  }
});

And then CSS to position accordingly…

Before 3.3.1

.carousel-inner .active.left { left: -33%; }
.carousel-inner .next        { left:  33%; }

After 3.3.1

.carousel-inner .item.left.active {
  transform: translateX(-33%);
}
.carousel-inner .item.right.active {
  transform: translateX(33%);
}

.carousel-inner .item.next {
  transform: translateX(33%)
}
.carousel-inner .item.prev {
  transform: translateX(-33%)
}

.carousel-inner .item.right,
.carousel-inner .item.left { 
  transform: translateX(0);
}

This will show 3 at time, but only slide one at a time:
