Hi there.

I have this table in my DB:

Group

 - ID-Name
 - 1 -abc
 - 2 -def
 - 3 -ghi

Pages

 - id-group_id-name
 - 1 -1       -home
 - 2 -1       -about us

Now I wanted to make a select box that groups them by 'group' using:

function add() {

$this->set('pages', $this->Page->find('list', array('fields' => array('Page.id', 'Page.name', 'Page.group_id'))));

}

In my add.ctp:

echo $form->input('group_id', array('options' => $pages));

The output:

<select name="data[Page][id]" id="PageId">
<optgroup label="1">
<option value="1">Home</option>
<option value="2">About Us</option>
</optgroup>
</select>

I wanted the optgroup to display the actual group name not the group id like:

<select name="data[Page][id]" id="PageId">
<optgroup label="abc">
<option value="1">Home</option>
<option value="2">About Us</option>
</optgroup>
</select>

I have tried this one:

$this->Page->find('list', array('conditions' => 'Group.id = Page.id', 'fields' => array('Page.id', 'Page.name', 'Group.name')));

But 'Group.id' and 'Group.name' is unknown.

Thanks!
