Hello, tell me please, is it possible to make a selection of errors? A person tries to add an ad, skips the required field, click “publish” and (now) the system subscribes the person to the field that he missed. Question: is it possible to highlight this field in red so that the person immediately understands which field he missed?
This depends on the browser implementation – HivePress just marks fields as “required”. For example, Chrome should display some notice above the required field, but if you mean changing the border color on form submission this requires CSS or JS customizations.
