How can we update the Form fields that have been modified by users without making changes to the remaining fields?

One possible solution would be to use AJAX (Asynchronous JavaScript and XML) to send the form data to the server as the user fills it out. Whenever a field is modified, the corresponding data is sent to the server and stored in the database. This way, only the modified fields are updated, while the remaining fields remain unchanged.

Another solution would be to use local storage to save the form data as the user types it. When the user submits the form, only the modified fields are sent to the server, while the remaining fields are retrieved from local storage and sent along with them. This approach can help reduce server load and improve performance.

Overall, there are multiple ways to update only the modified form fields without affecting the remaining fields. The best approach will depend on the specific requirements of your application and the technology stack you are using.
