Multilingual Forms Lang Management

Imported From: http://groups.google.com/group/in-portal-dev/browse_thread/thread/4a768190020c2b58#

Hi guys,

I'm working a lot actually with suggest forms, and I'd suggest to manage
langs the same way we are doing in admin: only 1 lang selector to switch all
content fields.
Actually we have flags, and when you have many custom fields, you need to
click on flags to change langs.

Is there an easy way to optionaly switch to a single dropdown lang selector
in forms?

thanks
Phil.
