Yes, users can edit their submissions even after they have sent them. To enable this feature, open the Advanced section of your form.
From the Submissions tab, tick the option Allow respondents to edit delivered submissions at a later time.
A new option will display – Resend notifications every time the submission is edited. Enable this option to receive submission updates and select which email template you wish to send.
You can also set up an email notification to go automatically to your respondents with the link they need to access to edit the submission, as long as they have provided their email address on the form. Under Respondent email address dropdown, search for the field that collected the email address of your respondents.
After clicking the Submit button, on the Thank You page, your respondents will receive a link and instructions for using it. You can also send this link via email to your users by selecting the Email field in the Respondent email address dropdown from the same Advanced → Submissions tab.
When your users access that link, the form will open up in a lightbox. Form fields will contain the input users have provided and all content is editable. After making edits, users simply need to click on the Update Submission button to have the new content saved.
