title: How to conditionally render a large number of properties in a panelGrid
body: <p>I would like to render a group of name-value only if a value is not null (or another condition). This group of name is among other names and values which are always rendered.</p>
  
  <p>To format the page, I use a <code>&lt;h:panelGrid columns="2"&gt;</code>.</p>
  
  <p>If I use a <code>&lt;h:panelGroup rendered='thecondition'&gt;</code> the alignment does not work. I tried <code>&lt;ui:fragment&gt;</code> and it didn't work either.</p>
  
  <p>The group contains a large number of values and I would like not to add a rendered attribute for each name and each value of the group. Is there another solution?</p>
