title: Make JQuery UI Dialog automatically grow or shrink to fit its contents
body: <p>I have a JQuery UI dialog popup that displays a form.  By selecting certain options on the form new options will appear in the form causing it to grow taller.  This can lead to a scenario where the main page has a scrollbar and the JQuery UI dialog has a scrollbar.  This two-scrollbar scenario is unsightly and confusing for the user.</p>
  
  <p>How can I make the JQuery UI dialog grow (and possibly shrink) to always fit its contents without showing a scrollbar?  I would prefer that only a scrollbar on the main page is visible.</p>
