Dynamic nested widgets like ExtJS has.

Dynamic nested widgets like ExtJS has.

Hi,

It is possible to create nested widgets dynamically?
An example for a window with a tab panel:
http://www.sencha.com/deploy/dev/examples/window/hello.html
code:
http://www.sencha.com/deploy/dev/examples/window/hello.js

I want to create a complex one page app with jqueryui but I don't understand how to initialize complex nested widgets. Do I need to start each widget separately and use timeouts or events to make sure they are created at the correct order?

Thanks
