title: Only load div iframe onclick
body: <p>I have this part of code. When the page is loaded also all div's are loaded but not yet visible. Is the an way to start loading the content of the div when it's clicked? Now the page is slowed down because of all div's</p>
  
  <pre><code>&lt;a href="#?w=550" rel="popup_add_dossier" class="poplight" title="'.$lang['form_add'].'"&gt;&lt;img src="images/icon/new.png" &gt;&lt;/a&gt;
  
  &lt;div id="popup_add_dossier" class="popup_block"&gt;
  &lt;iframe src="add_dossier.php" frameborder="0" scrolling="no" width="550" height="400"&gt;
  </code></pre>
