select_month

Returns a select tag with options for each of the months January through December with the current month selected. The month names are presented as keys (what’s shown to the user) and the month numbers (1-12) are used as values (what’s submitted to the server). It’s also possible to use month numbers for the presentation instead of names – set the :use_month_numbers key in options to true for this to happen. If you want both numbers and names, set the :add_month_numbers key in options to true. If you would prefer to show month names as abbreviations, set the :use_short_month key in options to true. If you want to use your own month names, set the :use_month_names key in options to an array of 12 month names. If you want to display months with a leading zero set the :use_two_digit_numbers key in options to true. Override the field name using the :field_name option, ‘month’ by default.
