How did the DetailView of the Yiichina official website personal data come out?

The following is the Cdetailview display page for Yiichina's official profile:

Notice the right side, and if the value is empty, the display is not set. And it's pink.
This is the effect I wrote myself:

The main difference is the display of the value on the right. The official website right side of the value is not the time to show pink, and I here is directly blank.
I looked at the API and found that there was a cssclass this attribute. So I tried to write:

array(             'label'=>'关注',            'type'=>'raw',             'cssClass'=>'null',          'value'=>CHtml::link(CHtml::encode('查看我关注的人'),                              array('relations/followList')),        ),

It turns out that the label tag is getting pink, not the value being pink.
How can I write to make the value on the right turn pink, and not set when the values are empty, instead of being a blank as I write?

 $this->widget('zii.widgets.CDetailView', array(    'data'=>$model,    'attributes'=>array(        'id',        'name',        'description',        'directory',        'weight',        'created',        'modified',        //xxx不存在于model里边的属性时,会变红        'xxx',    

The value is judged in view. When the value is empty, the output is not set and a class with a pink effect is added to the label.
