Minimize List Divider Contents in Inonic

I developed a List divider with various items in it using Ionic http://ionicframework.com/docs/components/#item-dividers

<div class="list">

  <div class="item item-divider">
    Candy Bars
  </div>

  <a class="item" href="#">
    Butterfinger
  </a>
</div>

I would like to know if there is any method to hide the lists under Item-Divider, i.e. when I click Candy Bars, all the lists under it should hide. And on clicking again, it should reappear.
