We have Nintex form in SharePoint 2016 which contains MultiLine,Choice and Yes/No fields .
If user opens already existing item where data is already filled and on page load for form if script is added for form as disabled as below,
Then when you save next time.It saves empty value in the list.
Attached screenshot which explains above scenario.
Does disabled doesnt work in Nintex form for SharePoint 2016? Please let me know if we have any alternate option to fix such cases.
