title: JSF Component without own HTML element
body: <p>I am looking for a JSF 2.0 Component that is just an container for other components but do not produce own HTML elements.</p>
  
  <p>My situation is that I have an (already styled) jsf-xhtml component page. Now I need to disable a lot of the rendering.</p>
  
  <pre><code>&lt;ui:component&gt;
      &lt;h:panelGroup layout="block" rendered="#{not empty user.registrations}"&gt;...&lt;/&gt;
      &lt;h:panelGroup layout="block" rendered="#{not empty user.registrations}"&gt;...&lt;/&gt;
      &lt;h:panelGroup layout="block" rendered="#{not empty user.registrations}"&gt;...&lt;/&gt;
      &lt;h:panelGroup layout="block" rendered="#{not empty user.registrations}"&gt;...&lt;/&gt;
  &lt;/ui:component&gt;
  </code></pre>
  
  <p>But I do not want to specify the <code>rendered="#{not empty user.registrations}"</code> fore times. Instead I want to wrapp it with some component like:</p>
  
  <pre><code>&lt;ui:component&gt;
      &lt;xxxx  rendered="#{not empty user.registrations}"&gt;
          &lt;h:panelGroup layout="block"&gt;...&lt;/&gt;
          &lt;h:panelGroup layout="block"&gt;...&lt;/&gt;
          &lt;h:panelGroup layout="block"&gt;...&lt;/&gt;
          &lt;h:panelGroup layout="block"&gt;...&lt;/&gt;
      &lt;/xxxx&gt;
  &lt;/ui:component&gt;
  </code></pre>
  
  <p>Because the page is already styled (and I fear that this is done in a fragile way) I need an jsf-component (<code>xxxx</code>) that does NOT produce own html elements like <code>div</code> or so.
  Does such an jsf-component exit?</p>
