Is it possible to make a field mandatory

When I am in my shopping cart I would like to make the field “link note info” required.
How to do ?

If it is a user input element, then you should be able to tick the ‘make required’ checkbox in the element settings.

Otherwise you’ll need to add a little bit of code to make sure that the info box isn’t left blank.

Unfortunately I do not have the possibility to make it mandatory manually Could you help me for coding?

Does anyone were able to solve this? I’m with the same situation right now, I want to make the ‘Add note’ field mandatory but there are no UI options for that, and when I try to use Corvid, there is no Id for that field.
