复选框,复选框标签和之后的图像.

如何使用Zend Engine Form创建相同的视图

我尝试如下

$this->addElement(
            'CheckBox',"$key",array(
             'label'=>$value,'checkedValue' => "$key",'uncheckedValue' => '','checked' => true,'disabled' => false,)
        );

     $element = $this->getElement($key);         


       $element->setDecorators(
   array(
     'ViewHelper',array('Label',array('tag' => 'dt','class'=>'hidden')),array('Description',array('escape'=>false,'tag'=>' span')),//escape false because I want html output
    )
   );

     $element->setDescription('<img name="help_'.$key.'" id="help_'.$key.'" src="/application/modules/User/externals/images/what-is-this.gif"/>');

$element->setDescription('<img name="help_'.$key.'" id="help_'.$key.'" src="/application/modules/User/externals/images/what-is-this.gif"/>');

但是显示复选框,描述图像和复选框标签为上标.

请帮忙
