^{Originally posted by schiller-manuel February 8, 2024} After form submission I want to keep the form open and make the form pristine again, but don't want to lose the current values.

Inspiration: In RHF this is possible via calling reset with new values: https://www.react-hook-form.com/api/useform/reset/
