Display element outside of "overflow: hidden" in Swiper slider

Question

THE PROBLEM

I have a swiper slider: http://codepen.io/kerowan/pen/xqYrwJ (recreate problem for example by giving .product-info-wrapper a fixed height of around 100px)

In the slides, there is an image and an infobox, which initially looks like this:

When I click on "Kurzinfo", the box needs to expand and finally look like this (the .swiper-container ends just after the NEW badge, so it has to flow over the swiper-container):

The problem is, that .swiper-container has an overflow: hidden; attribute, to hide the slides that continue to the right side.

WHAT HAVE I TRIED?

1) I have tried changing overflow: hidden; on the .swiper-container to overflow-x: hidden; in an attempt to just hide the slides which flow to the right, but show stuff that overflows downwards. This results in .swiper-container just adding a scrollbar, which lets you scroll down to see the content that should overflow.

2) I have tried changing position: absolute; on .product-info-wrapper (which wraps the box and the badge) to position: fixed;, because I read that the overflow attribute is ignored by position: fixed;. This doesn't seem to solve the problem, however.

I have not tried anything else yet, simply because I don't know any other solution approach.

SNIPPET

I pasted the snippet here, but it won't work, because I used SCSS and unfortunately lack the time to rewrite it to pure CSS. Can be copied to codepen, though, if the link above should die.

$(document).ready(function() {
  var productsInFocus = new Swiper ('.products-in-focus', {
    nextButton: '.product-focus-next',
    prevButton: '.product-focus-prev',
    slidesPerView: 4,
    loop: false,
    spaceBetween: 20
  });
});

.content-wrapper {
  max-width: 1100px;
  margin: 0 auto;
}

.product-wrapper {
  position: relative;
  margin-bottom: 1rem * 5;
  margin-top: 1rem * 5;

I hope my question was clear enough. If you need more details, please let me know!

Answer 1

You can add:

.swiper-slide {
  padding-bottom: 30px;
}

where 30px is the value your badge should be beyond the border.

Answer 2

I found a solution, I feel like it's a bit of a hack, however. For what it's worth, here it is:

.swiper-container {
  overflow: visible;
}
$slide: ".swiper-slide";
.swiper-slide {
  opacity: 0;
  visibility: hidden;
  transition: opacity 200ms ease-in-out, visibility 200ms ease-in-out;
  &-active {
    opacity: 1;
    visibility: visible;

    @for $i from 1 through 3 {
      & + #{$slide} {
        opacity: 1;
        visibility: visible;
      }
      $slide: "#{$slide} + .swiper-slide";
    }
  }
}

So, what I do here is setting .swiper-container from overflow: hidden; to overflow: visible and then I tell every .swiper-slide to have opacity: 0; except for the &-active one. I then use the &-active slide as a starting point and iterate through a sass for-loop 3 times to add opacity: 1; for the next 3 .swiper-slides. This sass code produces the following pure css code (.swiper-container not included here)

.swiper-slide {
  opacity: 0;
  visibility: hidden;
  transition: opacity 200ms ease-in-out, visibility 200ms ease-in-out;
}
.swiper-slide-active {
  opacity: 1;
  visibility: visible;
}
.swiper-slide-active + .swiper-slide {
  opacity: 1;
  visibility: visible;
}
.swiper-slide-active + .swiper-slide + .swiper-slide {
  opacity: 1;
  visibility: visible;
}
.swiper-slide-active + .swiper-slide + .swiper-slide + .swiper-slide {
  opacity: 1;
  visibility: visible;
}

This whole stuff is just to remove the overflow: hidden; from .swiper-container while still showing only the slides I need to see and hiding the others. Now I can play around with the height of the Infobox and the effect I was looking for works.
