I am adding a dropdown custom field to my cases, but I want to have it as an "optional" field for the user to capture and fill. I've tried in vain, but can't seem to add a blank as the first option so that the user can hide the field and review it at their convenience.
Example: I have a list of applications where the user is experiencing a problem "MS Word", "MS Excel", "Web Mail". I'd like to make the field optional on the left to include in the case.
