CContentDecorator decorates the content it encloses with the specified view.

CContentDecorator is mostly used to implement nested layouts, i.e., a layout is embedded within another layout. CBaseController defines a pair of convenient methods to use CContentDecorator:
$this->beginContent('path/to/view');
// ... content to be decorated
$this->endContent();


The property view specifies the name of the view that is used to decorate the content. In the view, the content being decorated may be accessed with variable $content.
