Question

i want to create carousel using angular-carousel library. i want to display 3 slides at a time and while swiping it should swipe only one item.

here is the link for ref. angular-carousel :https://github.com/revolunet/angular-carousel

ex. 
//this is just html code
<ul rn-carousel class="image">
  <li ng-repeat="image in sportImages">
    <div class="layer">{{ image }}</div>
  </li>
</ul>
