Change Content like google?
<p>I'm trying to make a help page with a similar layout as <a href="http://support.google.com/plus/?hl=en" rel="nofollow">http://support.google.com/plus/?hl=en</a>. Could someone please give me some advice or example of the best way to get the new content list to load without having to reload the page.</p>

<p>If you look at the link and press on for example, "circles and streams it changes the list on the right hand side. </p>

<p>thank you in advance </p>
