We have a screen when we hide/disable a comment field based on a value in some dropdown. For some values of the dropdown the comment is shown, for other values it's hidden. For example, imagine a dropdown with a value "other" where for other the user can freely add some explanation.
Now, imagine the following scenario:
- User selects "other"
- User adds a comment
- User selects a different value that hides the comment
- User selects "other" again, so the comment field is visible again
What shall be the behavior of the comment field - should the comment from step 2 be retained or should it be empty?
