I want to resize a form automatically because of the not-you function. for example, a form for a event registration has got 10 fields (name, address etc.). if the visitor is known at the system, some fields are not visible because they are prefilled (just in the background). so it could be that there are only a little text and a button for registration to the event. in this case there is a lot of space between the button and the page footer.
I want to avoid this empty area. has somebody solved this issue? or do you have any ideas? it would be great.
