I have created a form giving a required field option which asks people how did you hear about us, one of the selections is titled 'other' which is what most people seem to click.
How could I make it so that if the 'other' option is selected that they are forced to provide more information perhaps by a description box opening but only when 'other' option is selected.
I know perhaps the easiest way would be not to have the other option, but I am trying to find out what marketing is working.
Thanks in advance of your assistance
