danielebarchiesi@0:  * To make a form auto submit, all you have to do is 3 things:
danielebarchiesi@0:  *
danielebarchiesi@0:  * ctools_add_js('auto-submit');
danielebarchiesi@0:  *
danielebarchiesi@0:  * On gadgets you want to auto-submit when changed, add the ctools-auto-submit
danielebarchiesi@0:  * class. With FAPI, add:
danielebarchiesi@0:  * @code
danielebarchiesi@0:  *  '#attributes' => array('class' => array('ctools-auto-submit')),
danielebarchiesi@0:  * @endcode
danielebarchiesi@0:  *
danielebarchiesi@0:  * If you want to have auto-submit for every form element,
danielebarchiesi@0:  * add the ctools-auto-submit-full-form to the form. With FAPI, add:
danielebarchiesi@0:  * @code
danielebarchiesi@0:  *   '#attributes' => array('class' => array('ctools-auto-submit-full-form')),
danielebarchiesi@0:  * @endcode
danielebarchiesi@0:  *
danielebarchiesi@0:  * If you want to exclude a field from the ctool-auto-submit-full-form auto submission,
danielebarchiesi@0:  * add the class ctools-auto-submit-exclude to the form element. With FAPI, add:
danielebarchiesi@0:  * @code
danielebarchiesi@0:  *   '#attributes' => array('class' => array('ctools-auto-submit-exclude')),
danielebarchiesi@0:  * @endcode
danielebarchiesi@0:  *
danielebarchiesi@0:  * Finally, you have to identify which button you want clicked for autosubmit.
danielebarchiesi@0:  * The behavior of this button will be honored if it's ajaxy or not:
danielebarchiesi@0:  * @code
danielebarchiesi@0:  *  '#attributes' => array('class' => array('ctools-use-ajax', 'ctools-auto-submit-click')),
danielebarchiesi@0:  * @endcode
danielebarchiesi@0:  *
danielebarchiesi@0:  * Currently only 'select', 'radio', 'checkbox' and 'textfield' types are supported. We probably
danielebarchiesi@0:  * could use additional support for HTML5 input types.
