//读取下拉菜单
public function actionList()
{		
    $criteria = new CDbCriteria;
    $criteria->condition = 't.type=:type';
    $criteria->params = array(':type'=>'product');
    $criteria->order = 't.id desc';
    $list = Category::model()->findAll($criteria);	
    $criteria = new CDbCriteria;
    $criteria->condition = 't.type=:type';
    $criteria->params = array(':type'=>'service');
    $criteria->order = 't.id desc';
    $list1 = Category::model()->findAll($criteria);
    $criteria = new CDbCriteria;
    $criteria->condition = 't.type=:type';
    $criteria->params = array(':type'=>'app');
    $criteria->order = 't.id desc';
    $list2 = Category::model()->findAll($criteria);		
    $criteria = new CDbCriteria;
    $criteria->condition = 't.type=:type';
    $criteria->params = array(':type'=>'brand');
    $criteria->order = 't.id desc';
    $list3 = Category::model()->findAll($criteria);
    $this->render('index',array('list'=>$list,'list1'=>$list1,'list2'=>$list2,'list3'=>$list3));
}
