Provide description column for the keys and values columns

Drupal 7 now has support for descriptions on individual checkboxes or radio buttons, but finding a syntax and UI that is logical for this functionality is difficult. In any case, whichever module you're using to create your checkboxes will need to support storing descriptions for checkboxes/radios also, which currently isn't the case for Field module or Webform.

Any update on this? I am also interested in adding an extra description to each option. I know this is possible for a single on/off checkbox or radio button via a simple form_alter. But I can't find this for a multiple checkboxes widget.

Edit: was not able to do this via hook_form_alter, but it is indeed possible via theme_preprocess_form_element().

In form_alter(), it is possible but it's a little difficult:

$form['options'] = array(
  '#type' => 'radios',
  '#options' => array(
    'one' => 'One',
    'two' => 'Two',
    'three' => 'Three',
  ),
);
$form['options']['one']['#description'] = t('Description for one');
$form['options']['two']['#description'] = t('Description for two');
$form['options']['three']['#description'] = t('Description for three');

But like I said above, no module currently supports adding descriptions to checkboxes/radio buttons (neither Field, nor CCK, nor Webform). I think a larger problem yet is figuring out a UI that would be appropriate for descriptions. I don't think just adding another field would be suitable, because then you'd end up with a sea of textfields between key, label, and description.

Hm, I realize re-reading this request that I misinterpreted it. I thought the request was to add support for "description" in addition to "key" and "value" columns. But the request was actually to set the labels for the "key" and "value" columns. I was thrown off by calling it descriptions, when we'd normally refer to these as labels (or table headers in this case). The original request is actually quite a bit simpler and possible to implement.

I need descriptions, too. Highly important feature...

This would be cool to add.

There is a programatic solution for adding checkbox descriptions:

$form['checkboxes'] = array(
'#type' => 'checkboxes',
'#title' => 'Checkboxes',
'#options' => array(
'foo' => 'Foo',
'bar' => 'Bar',
);
$form['checkboxes']['foo']['#description'] = 'description for the foo checkbox';

But changing the checkbox descriptions is not something that should require a code change. There should be a way for the client to change these in the GUI with content type edit permissions.
