Slick carousel - force slides to have the same height

Question

Im having trouble with the Slick carousel JS plugin with multiple slidesToShow which have different heights.

I need the Slides to have the same

Answer 1

Ok guys i found an easy solution. Just add a setPosition callback function (fires after position/size changes) which sets the height of the slides to the height of the slider (slideTrack):

JS

$('.slider').slick({
    autoplay: false,
    dots: false,
    infinite: false,
    arrows: false,
    slidesToShow: 2,
    slidesToScroll: 2,
  rows: 0
})
.on('setPosition', function (event, slick) {
    slick.$slides.css('height', slick.$slideTrack.height() + 'px');
});

Dont forget that your slides need to have full height:

CSS

.slide {
  height: 100%;
}

Here's an SCSS-only solution if you're OK with using object-fit:

.slick {
  .slick-track {
    display: flex;

    .slick-slide {
      display: flex;
      height: auto;

      img {
        height: 100%;
        object-fit: cover;
        object-position: center;
      }
    }
  }
}
