    Is there a way to constrain the allowed values in a number field?

    I'm creating a bidding form, and want to limit the minimum bid and also the bidding increments (if possible)

    Number fields can have a set minimum and maximum.  However, number fields do not allow for setting increments.  To allow for both a min/max value and stepping, use a spinner field instead:

    Number fields have the min/max value option in the same place, though they do not have the stepping option.
