In Drupal I have defined a content type with a Year-Month date field in it. Content of this type has two drop downs on the edit form, one for Year and one for Month.
How can I change the Month drop down to show:
The values for each month range should be the same for the initial month in the range, i.e. 01, 03, 05, etc (I assume that these are the values for the months concerned in the normal Month drop down).
