/**
|
||
|
|
* 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 {@link tabs} property.
|
||
|
|
* The {@link tabs} property takes an array with tab ID being mapped tab definition.
|
||
|
|
* Each tab definition is an array of the following structure:
|
||
|
|
* <ul>
|
||
|
|
* <li>title: the tab title.</li>
|
||
|
|
* <li>content: the content to be displayed in the tab.</li>
|
||
|
|
* <li>view: the name of the view to be displayed in this tab.
|
||
|
|
* The view will be rendered using the current controller's
|
||
|
|
* {@link CController::renderPartial} method.
|
||
|
|
* When both 'content' and 'view' are specified, 'content' will take precedence.
|
||
|
|
* </li>
|
||
|
|
* <li>url: a URL that the user browser will be redirected to when clicking on this tab.</li>
|
||
|
|
* <li>data: array (name=>value), this will be passed to the view when 'view' is specified.</li>
|
||
|
|
* </ul>
|
||
|
|
*
|
||
|
|
* For example, the {@link tabs} property can be configured as follows,
|
||
|
|
* <pre>
|
||
|
|
* $this->widget('CTabView', array(
|
||
|
|
* 'tabs'=>array(
|
||
|
|
* 'tab1'=>array(
|
||
|
|
* 'title'=>'tab 1 title',
|
||
|
|
* 'view'=>'view1',
|
||
|
|
* 'data'=>array('model'=>$model),
|
||
|
|
* ),
|
||
|
|
* 'tab2'=>array(
|
||
|
|
* 'title'=>'tab 2 title',
|
||
|
|
* 'url'=>'http://www.yiiframework.com/',
|
||
|
|
* ),
|
||
|
|
* ),
|
||
|
|
* ));
|
||
|
|
* </pre>
|
||
|
|
*
|
||
|
|
* By default, the first tab will be activated. To activate a different tab
|
||
|
|
* when the page is initially loaded, set {@link activeTab} to be the ID of the desired tab.
