和Java Swing中类似Yii Framework 中的Layout 也允许嵌套，这是通过CContentDecorator来实现的，不过代码中并不需要直接使用CContentDecorator ，而是在定义layout使用

**\[php\]** [ view plain][view plain] [copy][view plain] [print][view plain] [?][view plain]

1.  $this\->beginContent('path/to/view');
2.  // ... content to be decorated
3.  $this\->endContent();

$this->beginContent('path/to/view');
    // ... content to be decorated
    $this->endContent();

其中view 为另外一个布局。

本例定义四个Layout，一个嵌套一个：
