Is there a plugin for modX to save completed forms?

Question

MODX

Of course, there is FormIt, but it only sends to e-mail, but it would be necessary to somehow store applications in the admin panel so that the form is the same as mine (as is the case with FormIt)

Answer 1

FormSave

Answer 2

FormIt has a concept of "hooks" with which form data is processed. Sending data to E-mail is far from the main functionality, it is implemented by one of the built-in hooks. You need to write your own, saving data in the database.
