title: Add class to h1-tag (into formatselect) - TinyMCE / Wordpress
body: <p>I would like to add a class to my "formatselect" options of the tinyMCE in Wordpress. So when selecting a h1 from the dopdown it should generate a <code>&lt;h1 class="blue"&gt;</code>.</p>
  
  <p>I found <a href="https://stackoverflow.com/questions/781549/tinymce-using-css-class-attributes-with-the-formatselect-dropdown-formats">this Post</a>, but can't get it to work.</p>
  
  <p>Any ideas?</p>
  
  <p>Thanks in advance!</p>
