I try to create dropdown-list with Yii, using listData and activeDropDownList.
I use the examples found on the web, but it refuses to create the optgroups for me.
$data = CHtml::listData(MyModel::model()->getEntries(0), 'id', 'text', 'group');
Generates an array as expected:
Array([group1] => Array([10]=>FirstEntry, [20]=>SecondEntry),
[group2]=>Array([30]=>firstEntryGroup2, [40]=>firstEntryGroup2))
And so on. So it's an associative array filled with sub-arrays...
But when I use
echo CHtml::activeDropDownList($model, 'dropdownName', $data);
All I get is a flat dropdown without the optgroups. Just the entries from the sub-arrays...
Yii 1.1.6 (I read something about safe-attributes and tried to implement it, but with no success...
The old answer below is incorrect. Sorry. You create optgroups using a 'group' attribute in your drop down data array.
array(
array('id'=>256,'text'=>'TV','group'=>'Electrical'),
array('id'=>257,'text'=>'Radio','group'=>'Electrical'),
);

Old answer:
There is a great gist here that shows how do create what you're after: https://gist.github.com/StandardNerd/2909111
<?php echo CHtml::dropDownList('Cars', 'car_id', array(
'Mazda'=>array(
'mazda-rx7'=>'RX7',
'mazda-rx5'=>'RX5',
),
'Volvo'=>array(
'volvo-b9tl'=>'B9TL',
'volvo-l90e-radlader'=>'L90E Radlader',
),
)); ?>
You're currently using an activeDropDownList which should only be different because you add your $model variable instead of 'Cars' and tweak the function
One of solutions is anonymous function.
$data = CHtml::listData(
MyModel::model()->getEntries(0),
'id',
'text',
function(MyModel $aMyModelInstance){
return $aMyModelInstance->getLocalizedGroupNameForThisInstance();
});
