I have contact form where customer can choose topic of the message from dropdown list.
Is it possible to add different "send to" address for one of these topics (probably via addons/form_builder/func.php) without creating extra contact form just for this topic?
Yes it works with several emails comma separated, but it is not the case since the messages from specific topic should only come to one specific address.
Would it work to assign extra conditional $sender in addons/form_builder/func.php. Something like, if elm X = 10, sender is Y ?
