Jquery – slick carousel inside accordion is broken when setting the variableWidth to false?

If you click the Collapsible Group Items #1 the slick inside of it is broken when setting the variableWidth: false. But if you set it to variableWidth: true it is working fine.

Here is the bootstrap doc https://bootstrapdocs.com/v3.3.5/docs/javascript/

See the codes below:

$(function() {
    $('.step-slider-a').slick({
      slidesToShow: 4,
      slidesToScroll: 1,
      arrows: true,
      infinite:false,
      dots: false,
      variableWidth: false,
      responsive: [
        {
          breakpoint: 992,
          settings: {
            slidesToShow:3,
          }
        },
        {
          breakpoint: 768,
          settings: {
            draggable:true,
            slidesToScroll:1,
            slidesToShow:1,
            centerMode:false,
            arrows: true,
            dots: false,
          }
        }
      ]
    });
    // $('a[data-toggle="collapse"]').on('shown.bs.collapse', function () {
    //   $('.step-slider-a').slick('setPosition');
    // })
});

    I have an alternative solution for this slick carousel inside accordion. First this is not the perfect solution because there is a glitch to its slick height especially on first load or every time you refresh the page.

    I will keep this question open just in case others have better solutions than mine.

    Updates:

    • I added css to target collapsing and collapse.in classes.
    • I updated the shown.bs.collapse for my accordion.

    Below is the updated code:

    $(function() {
    $('.step-slider-a').slick({
      slidesToShow: 4,
      slidesToScroll: 1,
      arrows: true,
      infinite:false,
      dots: false,
      variableWidth: false
    });
      // Reinitialize Slick Carousel on accordion shown. You can use reinit or setPosition
    $('#accordion').on('shown.bs.collapse', function (e) {
      $(e.target).find('.step-slider-a').slick('reinit');
    });
});
    .accordion-styles {
    & .collapsing {
      opacity: 0 !important;
    }

    & .collapse.in {
      opacity: 1 !important;
    }
    & .slick-prev:before, 
    & .slick-next:before {
      color:green;
    }
}

    To address this, you’ll need to listen to Bootstrap’s collapse events (shown.bs.collapse and hidden.bs.collapse) and force Slick Slider to update its layout when these events occur.

    Here’s how you can achieve this:

     $(function () {
            // Initialize Slick Slider
            $('.step-slider-a').slick({
                slidesToShow: 4,
                slidesToScroll: 1,
                arrows: true,
                infinite: false,
                dots: false,
                variableWidth: false,
                responsive: [
                    {
                        breakpoint: 992,
                        settings: {
                            slidesToShow: 3,
                        }
                    },
                    {
                        breakpoint: 768,
                        settings: {
                            draggable: true,
                            slidesToScroll: 1,
                            slidesToShow: 1,
                            centerMode: false,
                            arrows: true,
                            dots: false,
                        }
                    }
                ]
            });

            // Recalculate Slick Slider layout when collapse is shown
            $('#accordion').on('shown.bs.collapse', function () {
                $('.step-slider-a').slick('setPosition');
            });

            // Recalculate Slick Slider layout when collapse is hidden
            $('#accordion').on('hidden.bs.collapse', function () {
                $('.step-slider-a').slick('setPosition');
            });

        });
