Check if dropdown contains "-" or something else
There is a dropdown menu with the following values:
- "-"
- value 1
- Value 2
- Value 3
" - " is a default value and is always displayed first
(comparatively with zero)
However, a warning should appear as soon as you have not changed the value " - " to "Value 1, 2 or 3" when you save or exit the PDF. But you are not forced to change the value this is only a warning.
As a warning should appear: "Please choose a valid value (- is not a valid value)".
Thank you very much for the help!
