Show part of next and previous items with Owl Carousel 2.0

Question

I'm using Owl Carousel 2.0. I would like to show one item, a half (or less) of the previous item (left side) and a half (or less) of the next item (right side). Just putting a part of them out on the right and on the left side:

I've been trying using just CSS (padding and margin negative with the owl-stage-outer) but obviously Javascript override them.

Here's my code so far:

$('.owl-carousel').owlCarousel({
  loop: true,
  margin: 10,
  nav: true,
  responsive: {
    0: {
      items: 1
    },
    600: {
      items: 3
    }
  }
})

.owl-carousel .item h4 {
  color: #FFF;
  font-weight: 400;
  margin-top: 0em;
}

.owl-carousel .item {
  height: 10em;
  background: #4DC7A0;
  padding: 1em;
}

.wrapper {
  width: 40em;
}

<script src="//cdnjs.cloudflare.com/ajax/libs/OwlCarousel2/2.2.1/owl.carousel.min.js"></script>

<div class="wrapper">
  <div class="owl-carousel">
    <div class="item">
      <h4>1</h4>
    </div>
    <div class="item">
      <h4>2</h4>
    </div>
    <div class="item">
      <h4>3</h4>
    </div>
    <div class="item">
      <h4>4</h4>
    </div>
    <div class="item">
      <h4>5</h4>
    </div>
    <div class="item">
      <h4>6</h4>
    </div>
    <div class="item">
      <h4>7</h4>
    </div>
    <div class="item">
      <h4>8</h4>
    </div>
    <div class="item">
      <h4>9</h4>
    </div>
    <div class="item">
      <h4>10</h4>
    </div>
    <div class="item">
      <h4>11</h4>
    </div>
    <div class="item">
      <h4>12</h4>
    </div>
  </div>

Answer 1

The easiest way to do this is by using stagePadding. Demo below:

$(function() {
  $('.owl-carousel').owlCarousel({
    margin: 10,
    loop: true,
    items: 1,
    stagePadding: 100
  });
});

<script src="//ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<link href="//cdnjs.cloudflare.com/ajax/libs/OwlCarousel2/2.2.1/assets/owl.carousel.min.css" rel="stylesheet" />
<script src="//cdnjs.cloudflare.com/ajax/libs/OwlCarousel2/2.2.1/owl.carousel.min.js"></script>

<div class="owl-carousel">
  <div class="item"><img src="//placehold.it/350x150&text=1" /></div>
  <div class="item"><img src="//placehold.it/350x150&text=2" /></div>
  <div class="item"><img src="//placehold.it/350x150&text=3" /></div>
  <div class="item"><img src="//placehold.it/350x150&text=4" /></div>
  <div class="item"><img src="//placehold.it/350x150&text=5" /></div>
  <div class="item"><img src="//placehold.it/350x150&text=6" /></div>
  <div class="item"><img src="//placehold.it/350x150&text=7" /></div>
  <div class="item"><img src="//placehold.it/350x150&text=8" /></div>
</div>

Answer 2

I used half values in the custom code like the above. Hope it helps.

$("#owlCarousel").owlCarousel({
  itemsCustom: [
    [0, 1],
    /* Show half of next item */
    [450, 1.5],
    [600, 2.5],
    [700, 3],
    [800, 3],
    [1000, 4],
    [1200, 4],
    [1400, 4],
    [1600, 4]
  ],

  lazyLoad: true,
  navigation: false,
});
