Usage it in your code

add hammer.js in your html

<script src="../node_modules/hammerjs/hammer.js"></script>

You are ready. use it in your template

<ul ngui-sortable>
  <li id="order">Order</li>
  <li id="me">Me</li>
  <li id="right">Right</li>
  <li id="the">The</li>
  <li id="into">Into</li>
  <li id="put">Put</li>
</ul>

Without css, it still works, but for better styling, please use some css. e.g.;

ul[ngui-sortable] {
   padding: 10px; 
   border: 1px solid #ccc;
  list-style: none; 
  display: block
}
ul[ngui-sortable] li {
  padding: 10px 5px;
  background: #4986e7;
  color: #fff; 
  border: 1px solid #fff;
  display: block; 
  position: relative
}
ul[ngui-sortable] li.drag-enter {
  border-top: 2px solid yellow;
}
