Can I add Please Select option in my dropdown list?

Yes, you can add Please Select to your dropdown lists. Type this: *Please Select* as the first option in the list. It will not be considered a valid choice; it’s simply an invitation to make one. In other words, if the dropdown list is a required field and the user leaves the first line selected, then they will get an error asking them to make a choice.
