Make JQuery UI Dialog automatically grow or shrink to fit its contents

Question

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.

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.

Update: As of jQuery UI 1.8, the working solution (as mentioned in the second comment) is to use:

width: 'auto'

Use the autoResize:true option. I'll illustrate:

  <div id="whatup">
    <div id="inside">Hi there.</div>
  </div>
   <script>
     $('#whatup').dialog(
      "resize", "auto"
     );
     $('#whatup').dialog();
     setTimeout(function() {
        $('#inside').append("Hello!<br>");
        setTimeout(arguments.callee, 1000);
      }, 1000);
   </script>
