* @file
|
| 3 |
* Provides dependent visibility for form items in CTools' ajax forms.
|
| 4 |
*
|
| 5 |
* To your $form item definition add:
|
| 6 |
* - '#process' => array('ctools_process_dependency'),
|
| 7 |
* - '#dependency' => array('id-of-form-item' => array(list, of, values, that,
|
| 8 |
* make, this, item, show),
|
| 9 |
*
|
| 10 |
* Special considerations:
|
| 11 |
* - Radios are harder. Because Drupal doesn't give radio groups individual IDs,
|
| 12 |
* use 'radio:name-of-radio'.
|
| 13 |
*
|
| 14 |
* - Checkboxes don't have their own id, so you need to add one in a div
|
| 15 |
* around the checkboxes via #prefix and #suffix. You actually need to add TWO
|
| 16 |
* divs because it's the parent that gets hidden. Also be sure to retain the
|
| 17 |
* 'form_process_checkboxes' in the #process array, because the CTools process will
|
| 18 |
* override it.
