Bootstrap carousel multiple frames at once

Question

This is the effect I'm trying to achieve with Bootstrap 3 carousel

Instead of just showing one frame at a time, it displays N frames slide by side. Then when you slide (or when it auto slides), it shifts the group of slides like it does.

Can this be done with bootstrap 3's carousel? I'm hoping I won't have to go hunting for yet another jQuery plugin...

Answer 2

This is what worked for me. Very simple jQuery and CSS to make responsive carousel works independently of carousels on the same page. Highly customizable but basically a div with white-space nowrap containing a bunch of inline-block elements and put the last one at the beginning to move back or the first one to the end to move forward. Thank you insertAfter!

$('.carosel-control-right').click(function() {
  $(this).blur();
  $(this).parent().find('.carosel-item').first().insertAfter($(this).parent().find('.carosel-item').last());
});
$('.carosel-control-left').click(function() {
  $(this).blur();
  $(this).parent().find('.carosel-item').last().insertBefore($(this).parent().find('.carosel-item').first());
});

@media (max-width: 300px) {
  .carosel-item {
    width: 100%;
  }
}
@media (min-width: 300px) {
  .carosel-item {
    width: 50%;
  }
}
@media (min-width: 500px) {
  .carosel-item {
    width: 33.333%;
  }
}
@media (min-width: 768px) {
  .carosel-item {
    width: 25%;
  }
}
.carosel {
  position: relative;
  background-color: #000;
}
.carosel-inner {
  white-space: nowrap;
  overflow: hidden;
  font-size: 0;
}
.carosel-item {
  display: inline-block;
}
.carosel-control {
  position: absolute;
  top: 50%;
  padding: 15px;
  box-shadow: 0 0 10px 0px rgba(0, 0, 0, 0.5);
  transform: translateY(-50%);
  border-radius: 50%;
  color: rgba(0, 0, 0, 0.5);
  font-size: 30px;
  display: inline-block;
}
.carosel-control-left {
  left: 15px;
}
.carosel-control-right {
  right: 15px;
}
.carosel-control:active,
.carosel-control:hover {
  text-decoration: none;
  color: rgba(0, 0, 0, 0.8);
}

    });

Answer 4

All the above solutions are hacky and buggy. Don't even try. Use other libs. The best I have found - http://sachinchoolur.github.io/lightslider Works great with bootstrap, does not add junk html, highly-configurable, responsive, mobile-friendly etc...

$('.multi-item-carousel').lightSlider({
    item: 4,
    pager: false,
    autoWidth: false,
    slideMargin: 0
});

Answer 5

I had the same problem and the solutions described here worked well. But I wanted to support window size (and layout) changes. The result is a small library that solves all the calculation. Check it out here: https://github.com/SocialbitGmbH/BootstrapCarouselPageMerger

To make the script work, you have to add a new <div> wrapper with the class .item-content directly into your .item <div>. Example:

<div class="carousel slide multiple" id="very-cool-carousel" data-ride="carousel">
    <div class="carousel-inner" role="listbox">
        <div class="item active">
            <div class="item-content">
                First page
            </div>
        </div>
        <div class="item active">
            <div class="item-content">
                Second page
            </div>
        </div>
    </div>
</div>

Usage of this library:

socialbitBootstrapCarouselPageMerger.run('div.carousel');

To change the settings:

socialbitBootstrapCarouselPageMerger.settings.spaceCalculationFactor = 0.82;

Example:

As you can see, the carousel gets updated to show more controls when you resize the window. Check out the watchWindowSizeTimeout setting to control the timeout for reacting to window size changes.

Answer 6

This is a working twitter bootstrap 3.

Here is the javascript:

$('#myCarousel').carousel({
    interval: 10000
})

$('.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 the css:

.carousel-inner .active.left  { left: -33%;             }
.carousel-inner .active.right { left: 33%;              }
.carousel-inner .next         { left: 33%               }
.carousel-inner .prev         { left: -33%              }
.carousel-control.left        { background-image: none; }
.carousel-control.right       { background-image: none; }
.carousel-inner .item         { background: white;      }

You can see it in action at this Jsfiddle

The reason i added this answer because the other ones don't work entirely. I found 2 bugs inside them, one of them was that the left arrow generated a strange effect and the other was about the text getting bold in some situations witch can be resolved by setting the background color so the bottom item wont be visible while the transition effect.
