MaterializeCSS resets active change icon.

Question

I am looking for some help with a picky one. I try to change the icon in the headers when they are active, but cannot solve the problem if I click on another heading without closing the first one that displays the corresponding icon.

Here is the code with an example of my problem. http://codepen.io/FPC/pen/xZEWVY

here is my code:

<div class="container">
  <div class="row">
    <div class="col s6">
      <ul class="collapsible popout" data-collapsible="accordion">
        <li>
          <div class="collapsible-header">
            <i class="material-icons right more">expand_more</i>
            <i class="material-icons right less" style="display: none">expand_less</i>
            Article Title
          </div>
          <div class="collapsible-body">
            <p>
              Content Snipit        
            </p>
          </div>
        </li>
        <li>
          <div class="collapsible-header">
            <i class="material-icons right more">expand_more</i>
            <i class="material-icons right less" style="display: none">expand_less</i>
            Article Title
          </div>
          <div class="collapsible-body">
            <p>
              Content Snipit
            </p>
          </div>
        </li>
        <li>
          <div class="collapsible-header">
            <i class="material-icons right more">expand_more</i>
            <i class="material-icons right less" style="display: none">expand_less</i>
            Article Title
          </div>
          <div class="collapsible-body">
            <p>
              Content Snipit
            </p>
          </div>
        </li>
      </ul>
    </div>
  </div>
</div>

here is js i'm using

    $(document).ready(function(){
  $( ".collapsible-header" ).click(function() {
      $(".more",this).toggle()
      $(".less", this).toggle()
  });
});

Answer 1

You do not need javascript for this

remove javascript and use only css

HTML

<ul class="collapsible" data-collapsible="accordion">
  <li>
      <div class="collapsible-header">
       <i class="material-icons">expand_less</i>First</div>
   </li>
   <li>
      <div class="collapsible-header">
       <i class="material-icons">expand_less</i>Second</div>
   </li>
</ul>

CSS

  .collapsible li.active i {
  -ms-transform: rotate(180deg); /* IE 9 */
  -webkit-transform: rotate(180deg); /* Chrome, Safari, Opera */
  transform: rotate(180deg);
}

Answer 2

Hakan answer, collapsible-header, ( ). CSS, :

CSS

.collapsible-header.active i {
-ms-transform: rotate(180deg); /* IE 9 */
-webkit-transform: rotate(180deg); /* Chrome, Safari, Opera */
transform: rotate(180deg);
}

Answer 3

The above two solutions still flip the other icons in the collapsible header in reverse. The ideal solution is to add a class to the icon.

<div class="collapsible-header">
<i class="material-icons vertical-align">filter_drama</i>
Header 1
<i class="material-icons right expand">expand_less</i>
</div>

Notice that the class "expand" is created. CSS will be similar to the two above, "expand" will just be created

.collapsible-header.active i.expand {
    -ms-transform: rotate(180deg); /* IE 9 */
    -webkit-transform: rotate(180deg); /* Chrome, Safari, Opera */
    transform: rotate(180deg);
  }
