Subject: [flexcoders] dynamic textArea sizing
Is there a way for the textArea to size its Height to fit the text, as
apposed to setting a height in pixels? I don't want the scroll bars
and it's no good for printing.
Any examples out there?
Thanks,
Mark

Using the Textfield made the trick I also set to off the scroll policies
so they wouldn't show
Thanks
