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 plaincopyprint?

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

[php] view plaincopyprint?

///main.php
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title><?php echo Yii::app()->name; ?></title>
</head>
<body>
<h1>Widget Demo</h1>
<?php echo $content; ?>
</body>
</html>
///row1.php
<?php $this->beginContent('/layouts/row2'); ?>
<div>
<?php echo $content; ?>
</div>
<p />
<div>
<?php echo 'row1 part'; ?>
</div>
<?php $this->endContent(); ?>
//row2.php
<?php $this->beginContent('/layouts/row3'); ?>
<div>
<?php echo $content; ?>
</div>
<p />
<div>
<?php echo 'row2 part'; ?>
</div>
<?php $this->endContent(); ?>
///row3.php
<?php $this->beginContent('/layouts/main'); ?>
<div>
<?php echo $content; ?>
</div>
<p />
<div>
<?php echo 'row3 part'; ?>
</div>
<?php $this->endContent(); ?>

///main.php<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title><?php echo  Yii::app()->name;    ?></title></head><body><h1>Widget Demo</h1><?php echo $content; ?></body></html>///row1.php<?php $this->beginContent('/layouts/row2'); ?><div><?php echo $content; ?></div><p /><div><?php echo 'row1 part'; ?></div><?php $this->endContent(); ?>//row2.php<?php $this->beginContent('/layouts/row3'); ?><div><?php echo $content; ?></div><p /><div><?php echo 'row2 part'; ?></div><?php $this->endContent(); ?>///row3.php<?php $this->beginContent('/layouts/main'); ?><div><?php echo $content; ?></div><p /><div><?php echo 'row3 part'; ?></div><?php $this->endContent(); ?>
