How to use CF7 for user registration?

Hello @mplusplus,

This question it’s an advanced customization you want to apply to your form, which is outside the scope of the plugin support forum. Contact Form 7 isn’t a registration form, but a contact form plugin.

However, you may check this code snippet: Contact Form 7 User Registration, or this third-party plugin extension Frontend Registration – Contact Form 7.

Best regards,
Yordan.

Thanks so much @yordansoares.
