title: How to have jQueryUI dialog box dynamically load content
body: <p>I love jQueryUI's dialog boxes.  However, there doesn't seem to be a way to dynamically load content built-in.  I guess I have to use some other approach to achieve this?  Will iframes load content only when they're made visible?  Is that the right way to do this?</p>
  
  <p>I'm open to other dialog box mechanisms if they're more suited for loading the content only when they're first opened.</p>
