title: How to apply filter when page load?
body: <p>Filters have this code:</p>
  
  <pre class="lang-css prettyprint-override"><code>&lt;li style="float:left; width:70px; padding-left: 10px;"&gt;&lt;a href="#none" data-filter=".film"&gt;&lt;img src="img/study.png" width="70"&gt;&lt;/a&gt;&lt;/li&gt;
  &lt;li style="float:left; width:70px; padding-left: 10px;"&gt;&lt;a href="#none" data-filter=".music"&gt;&lt;img src="img/study.png" width="70"&gt;&lt;/a&gt;&lt;/li&gt;
  &lt;li style="float:left; width:70px; padding-left: 10px;"&gt;&lt;a href="#none" data-filter=".art"&gt;&lt;img src="img/study.png" width="70"&gt;&lt;/a&gt;&lt;/li&gt;
  </code></pre>
  
  <p>I want to create an autoload for a filter when starting the page.
  The main in the filter is: </p>
  
  <pre><code>data-filter=".music"
  </code></pre>
  
  <p>But I dont know automatically call this filter when starting the page. How do I do that?</p>
