title: Pass Data to template files in liferay
body: <p>I would like to pass data such as <strong>navigation items</strong> or <strong>languages supported</strong> to the portal_normal.vm file so that it gets displayed on the portal. </p>
  
  <p>I don't have a clue about how to do it. I've seen that in velocity files the data is passed in variables as follows:</p>
  
  <pre><code>    &lt;title&gt;$the_title - $company_name&lt;/title&gt;
  </code></pre>
  
  <p>I would like to do the same for <strong>navigation items</strong> and other data in my portal but I have no clue how.</p>
