title: How to not render whole block in JSF?
body: <p>Is there a JSF 2.1 component which lets me conditionally render (or not render) all its content? Something like</p>
  
  <pre><code>&lt;h:component rendered="#{user.loggedIn}"&gt;
  
  ...a bunch of jsf components and HTML code...
  ...even more HTML code...
  
  &lt;/h:component&gt;
  </code></pre>
  
  <p>I am using PrimeFaces 3M4 as this may influence your answer!</p>
