Carousel boostrap

I have this piece of code:

<div class="body">
   <div class="grid">
       <div class="item-grid">
           <div class="list">
               <div class="item-list">
                   <div class="item">

                   </div>
               </div>
           </div>
       </div>
   </div>
</div>

What i need to realize is a simple carousel that show at last 4 "item" concurrently. The actual css class I need it for some javascript that load data.

I can use bootstrap 3.3.7.
