I want to know how can i view the form details filled by user using the unique id number of their form.

i want to make a form in that when i type the unique id number it should display the form linked with that unique id number.

To add a unique ID to each form that is not the random submission ID, you can add a unique ID widget to your form:

While viewing your submissions, you can search for the ID to show the associated submission:
