function form_process_fieldset
form_process_fieldset(&$element, &$form_state)
Arranges fieldsets into groups.
Parameters
$element: An associative array containing the properties and children of the fieldset. Note that $element must be taken by reference here, so processed child elements are taken over into $form_state.
$form_state: The $form_state array for the form this fieldset belongs to.
Return value
The processed element.

function form_process_fieldset(&$element, &$form_state) { $parents = implode('][', $element['#parents']); // Each fieldset forms a new group.
