And how to open a jQuery UI Dialog without a title bar?
I figured out a fix for dynamically removing the title bar.

$("#example").dialog(dialogOpts);
// remove the title bar
$(".ui-dialog-titlebar").hide();

This will remove all elements with the class 'ui-dialog-titlebar' after the dialog box is rendered.
