php - Yii active dropdownlist with optgroup -

i seek create dropdown-list yii, using listdata , activedropdownlist.

i utilize examples found on web, refuses create optgroups me.

$data = chtml::listdata(mymodel::model()->getentries(0), 'id', 'text', 'group');

generates array expected:

array([group1] => array([10]=>firstentry, [20]=>secondentry), [group2]=>array([30]=>firstentrygroup2, [40]=>firstentrygroup2))

and on. it's associative array filled sub-arrays...

but when use

echo chtml::activedropdownlist($model, 'dropdownname', $data);

all flat dropdown without optgroups. entries sub-arrays...

yii 1.1.6 (i read safe-attributes , tried implement it, no success...

the old reply below incorrect. sorry. create optgroups using 'group' attribute in drop downwards info array.

array( array('id'=>256,'text'=>'tv','group'=>'electrical'), array('id'=>257,'text'=>'radio','group'=>'electrical'), );

old answer:

there great gist here shows how create 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 using activedropdownlist should different because add together $model variable instead of 'cars' , tweak function

php yii drop-down-menu
