   3  * To make a form auto submit, all you have to do is 3 things:
   4  *
   5  * ctools_add_js('auto-submit');
   6  *
   7  * On gadgets you want to auto-submit when changed, add the ctools-auto-submit
   8  * class. With FAPI, add:
   9  * @code
  10  *  '#attributes' => array('class' => array('ctools-auto-submit')),
  11  * @endcode
  12  *
  13  * If you want to have auto-submit for every form element,
  14  * add the ctools-auto-submit-full-form to the form. With FAPI, add:
  15  * @code
  16  *   '#attributes' => array('class' => array('ctools-auto-submit-full-form')),
  17  * @endcode
  18  *
  19  * If you want to exclude a field from the ctool-auto-submit-full-form auto submission,
  20  * add the class ctools-auto-submit-exclude to the form element. With FAPI, add:
  21  * @code
  22  *   '#attributes' => array('class' => array('ctools-auto-submit-exclude')),
  23  * @endcode
  24  *
  25  * Finally, you have to identify which button you want clicked for autosubmit.
  26  * The behavior of this button will be honored if it's ajaxy or not:
  27  * @code
  28  *  '#attributes' => array('class' => array('ctools-use-ajax', 'ctools-auto-submit-click')),
  29  * @endcode
  30  *
  31  * Currently only 'select', 'radio', 'checkbox' and 'textfield' types are supported. We probably
  32  * could use additional support for HTML5 input types.
