角度旋转木马有多个项目

Question

我想使用angular-carousel库创建轮播。     我想一次显示3张幻灯片，同时滑动它只能刷一个项目。

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>

lets assume i have 100 images and i want to display 3 image slides at a time. right now i am able to display one slide at a time . what should i do to display  3 slides at a time? any suggestion ?

any help would be really good.
