I have a 3-component iOS picker where the user picks the section, row, and seat of a venue. What is considered the best practice for labeling the components? I also don't want a valid default selection (e.g. "101", "A", "1").
I've thought of two options:
Put the labels above the picker with "(none)" as the default selection for each component.
Put the labels inside the picker as the default selections: "(Section)", "(Row)", and "(Seat)".
I'm thinking option 2 is best, but I'd like some feedback. Thanks!
