Widget type radio buttons and N/A I have a field so-called "Status" in my custome contact type. It is a List (integer) and widget type is "Radio buttons". I added two values for allowed values list:

 0|Sold
 1|Available


Default value is "Available". But Drupal lists this as below:

 () N/A
 () Sold
 () Available


Why does Drupal add this unnecessary "N/A" to the radio buttons? I encountered this problem since D6. Now, I'm using the latest version 7.14. I'm still seeing this.

I know I can remove the "N/A" by writing a hook from a custom module.
Nonetheless, I don't want to write additional codes for this kind of small thing. When I use "Select list", it is ok with an option "-None-", but the radio button is ideally suited for the two options.

How can I remove it without installing additional module? Am I missing some functionalities from Drupal core interface?
Something like this should help.

(function($) {
  $('.form-radio[value=_none]').parent().hide();
})(jQuery);
