title: jsf ui:repeat with multiple items in row
body: <p>Is it possible to iterate over collection and display multiple items in a row?
  Something like:</p>
  
  <pre><code>&lt;ui:repeat value="#{c.images}" var="img" step="3"&gt;
  #{img} #{img+1} #{img+2}&lt;br/&gt;&lt;br/&gt;
  &lt;/ui:repeat&gt;
  </code></pre>
