On registration , I cannot allow fields to be conditional . like if a user selects his/her profession , ask him/her to fill the further related info .

I created a feature request 5 years ago - https://github.com/PHPfox-Official/phpfox-v4-feature-requests/issues/302

Do you think this a "must" feature?

It is available on The top rival of phpFox.

I got this customization done sometime ago but that created issues in my site.

phpFox, please reward us for our loyalty. 

I am damn sure this is a hot feature
