Use:
<?=partial("X/__custom", array('form_primval'=>1))?>

X is name of the extended controller, form by default


Form builder:

  Form object
    - title
    - prefix (so table name etc)
    - content
    - terms_and_conditions
    - fields
    
    Field object
      - type (text / checkbox / radio / textarea / select)
      - grouping (hidden value to join multiple radios together etc)

      - title (label)
      
      - choices (new line separated options - for select only)
      
      - value (for radio / checkboxes)
      
      - required field
      
email setup uses a notification class, submission is the email view which is empty by default


include this in your js:

  jQuery(document).ready(function(){
    jQuery("form .check-in").hide();
  });
