How can you disable scroll bars in the jQuery UI dialog box?

I solved the problem like this:

.dialog({
  title: $(this).attr("data-dialog-title"),
  closeOnEscape: true,
  close: function () { $(this).remove() },
  draggable: true,
  position: 'center',
  width: 500,
  height: 'auto',
  modal: true,
  open: function (event, ui) {
    $('#myDialogId').css('overflow', 'hidden'); //this line does the actual hiding
  }
});
