Full-featured dialog examples wanted. (input forms)

Hi all,
did any one find a ui.dialog based demo, where dialog is not only with
2 buttons and 1 text label, but also, with different types of input
fields, perhaps, with validation and dynamic warnings fade-in panels?
The examples/tutorials showing how to adjust the positions and sizes
of the input fields are also desired.
a link is very appreciated, many thanks in advance!
regards
Valery
