function ajax_example_autocheckboxes_callback

Callback for autocheckboxes.

Callback element needs only select the portion of the form to be updated. Since #ajax['callback'] return can be HTML or a renderable array (or an array of commands), we can just return a piece of the form. See @link ajax_example_advanced.inc AJAX Advanced Commands for more details on AJAX framework commands.

Return value

array Renderable array (the checkboxes fieldset)
