Best way to enter time in an optional 12 hr format?
What's the best way for entering time in a 12-hour format?
It's easier to select from a radio button AM / PM but since this field is optional, what if they decided not to fill it out, they cannot unselect the radio button.
Here they're able to unselect AM/PM but defaulting to 'Select' but it's not as fast as just tapping a radio button.
Which is better? Or any other suggestions?
