Multiple Dialog Interface Web Application

Multiple Dialog Interface Web Application

Hi, recently Chrome has disabled showModalDialog without alternatives, I'm try to use JQuery UI Dialog to emulate it. I have a web application that emulate a MDI client app, my problem is when I open a dialog inside another dialog with more dimensions of parent dialog. The second dialog is bigger than the first, and how it's displayed inside, can't resize to entire view. Can any help me? Thanks a lot of!
