Open Dialog/Navigate to

Another question about opendialog...
Is it possible to use the actual browser window screen size for opening a page as dialog?

I got the problem that while adding data on a page, i should give the user the possibility to enter data on another page (because he wants to add a new entry in a drop down which is neccesary for the actual data input). When i navigate to the page for the new dropdown entry i must save the data the user has entered on the first page because its gone when i use navigate to. dont know how without great effort....so i try to use opendialog with the above problems and the problem that the opendialog page is to small (especially the width).

I hope a could explain my problem :slight_smile:
