title: Selectize not working inside Bootstrap panel
body: <p>I'm using selectize.js 0.10.1 with Bootstrap 3.0.1 in my project. When I have selectize combobox outside the collapsible Bootstrap panel, everything works great as you can see in the picture.

  <p>Working code:</p>
  
  <pre><code>&lt;section class="container"&gt;
      &lt;div class="row" style="margin-bottom: 20px"&gt;
          &lt;div class="col-lg-4"&gt;
              &lt;select id="zastoj" placeholder="Razlog zastoja" class="demo-default selectized"&gt;&lt;/select&gt;
          &lt;/div&gt;
      &lt;/div&gt;
  &lt;/section&gt;
  </code></pre>
  
  <p>When I have selectize combobox inside the collapsible panel, the combobox can not be opened/expanded on click, it looks like it's read-only.

  <p>Non-working code:</p>
  
  <pre><code>&lt;section class="container"&gt;
      &lt;div class="panel panel-primary"&gt;
          &lt;div class="panel-heading"&gt;
              &lt;h3 class="panel-title"&gt;Operacije&lt;/h3&gt;
          &lt;/div&gt;
          &lt;div id="collapseOne" class="panel-collapse collapse in"&gt;
              &lt;div class="panel-body"&gt;
                  &lt;select id="zastoj2" placeholder="Razlog škarta" class="demo-default selectized"&gt;&lt;/select&gt;
              &lt;/div&gt;
          &lt;/div&gt;
      &lt;/div&gt;
  &lt;/section&gt;
  </code></pre>
  
  <p>I got it to work when I use Bootstrap 2.3.2 and selectize.js 0.9 in this <a href="http://jsfiddle.net/tstancin/yaBPm/8/" rel="noreferrer">fiddle</a>, but I can't get it to work with Bootstrap 3.1.1 and selectize.js 0.9 in this <a href="http://jsfiddle.net/tstancin/bSq4X/" rel="noreferrer">fiddle</a>. I even tried selectize 0.10.1, but no luck.</p>
  
  <p>Can this be solved or is it some kind of version problem? I need to use Bootstrap 3.0+ in my project.</p>
