CTabView displays contents in multiple tabs.

At any time, only one tab is visible. Users can click on the tab header to switch to see another tab of content.

JavaScript is used to control the tab switching. If JavaScript is disabled, CTabView still manages to display the content in a semantically appropriate way.

To specify contents and their tab structure, configure the tabs property. The tabs property takes an array with tab ID being mapped tab definition. Each tab definition is an array of the following structure:

title: the tab title.
content: the content to be displayed in the tab.
view: the name of the view to be displayed in this tab. The view will be rendered using the current controller's CController::renderPartial method. When both 'content' and 'view' are specified, 'content' will take precedence.
url: a URL that the user browser will be redirected to when clicking on this tab.

For example, the tabs property can be configured as follows,

array(
    'tab1'=>array(
          'title'=>'tab 1 title',
          'view'=>'view1',
    ),
    'tab2'=>array(
          'title'=>'tab 2 title',
          'url'=>'http://www.yiiframework.com/',
    ),
)

By default, the first tab will be activated. To activate a different tab when the page is initially loaded, set activeTab to be the ID of the desired tab.
