Add default 'Select One' option to payment gateway drop down?
I've noticed that the payment gateway doesn't have an option to say "Select One..." like most drop downs. I don't want customers to be confused and think they only have one payment option. Particularly on mobile phones, where the drop-downs don't have an arrow and you have to actually click them to see other options.
Is there a way to add a default "Select one" to the payment gateway drop down?
