All inputs below are constrained by an Enforcer instance, which prevent form submission until each field has a value that matches one of its datalist option values.
Input will automatically fill with an option value when the entered value matches only one option. For example, entering "new y" will autofill "New York".
Focus will automatically shift to the next form element when a valid value is set.
Same as above, but disabled until value is at least 5 characters in length.
Matches must begin from the first character.
