title: Prism: Stacking controls in a region?
body: <p>My Prism app needs to insert buttons from several modules into a Shell region. The buttons will be stacked vertically, like the navigation buttons (Mail, Calendar, and so on) in Outlook 2010. I am using custom controls as buttons, so I don't need to worry about templating--my problem is the same as if I was inserting plain radio buttons.</p>
  
  <p>How do set up the region so that the buttons will appear stacked vertically? Thanks for your help.</p>
