In my survey, I checked “Allow the other option” as one of the choices for my gender question. This will cause a text box to appear so that the unlisted gender can be added by the participant. In preview mode, if other option is selected but nothing is written in the text box, there is a message indicating that a response is required. I don’t want to force participants to write in the text box. How can I make this message disappear and allow the participant to continue the survey even if they haven’t written anything in the text box? Thanks in advance for your help!
