In our application, we mark all the required fields with an asterisk and when user tries to perform an action without providing values for all the required fields, we display an error message next to the field, for which the value is missing.
Now, our users want us to remove required field validation for one of the fields and want us to display a popup asking for the value of the field.
I’ve heard Popups are really bad from a UX point of view. So, should we tell the user that popups are bad and continue with error messages next to the field or is it Okay to display a popup in this particular instance?
