good to know if the standard WP registration form could be made to follow the same required fields format/js as ACF, as the WordPress default does it server side and doesn’t put a * next to the fields like ACF.
We also prefer this. Currently, if you have an ACF required field, ACF has good validation. But if you forget the mandatory E-Mail field of WordPress then it submits and returns your form back Empty…. this could really be a good addtion to ACF to hook into this on the Front end / user registation or edit Profile pages.
