 * )
 *
 * [1st_element_name] => Array for the 1st element

 * [value] => element value,
 * [type] => type of the element
 * [frozen] => whether element is frozen
 * [label] => label for the element
 * [required] => whether element is required
 * // if element is not a group:
 * [html] => HTML for the element
 * // if element is a group:
 * [separator] => separator for group elements
 * [1st_gitem_name] => Array for the 1st element in group
