我有下拉列表
echo CHtml::dropDownList('personids', '',$list, array('id'=>'sea'.$dd,'class'=>'vulntr-textfld1','prompt'=>'Select',));
,列表数据是
$criteria=new CDbCriteria();
$criteria->addCondition('PersonTypeCode=:PersonTypeCode AND FamilyId=:FamilyId ');
$criteria->params=array(':PersonTypeCode'=>$category,':FamilyId'=>$Familyid);
$lookupval = Person::model()->findAll($criteria);
$list = CHtml::listData($lookupval, 'PersonID', 'FirstName');
它运作良好..但我的问题是如何在此下拉列表中选择多个值,请提出任何建议
