title: Flex LinkBar similar to iGoogle links
body: <p>I wanted to create a Flex LinkBar that looks similar to the iGoogle links. The links are expandable (one level-deep) by clicking on a plus button. I've considered styling a Tree or Accordion to get the desired look and feel. But before I spend time on one approach versus another, I thought to ask first.</p>
  
  <p>Does anyone know a component that I could use to achieve this? Or an example of someone doing a similar vertical navigation bar? It should only be one level deep and some parent nodes might not have children (doesn't expand).</p>
  
  <p>Thanks in advance....</p>
