/**
|
|
* MainMenu is a widget displaying main menu items.
|
|
*
|
|
* The menu items are displayed as an HTML list. One of the items
|
|
* may be set as active, which could add an "active" CSS class to the rendered item.
|
|
*
|
|
* To use this widget, specify the "items" property with an array of
|
|
* the menu items to be displayed. Each item should be an array with
|
|
* the following elements:
|
|
* - visible: boolean, whether this item is visible;
|
|
* - label: string, label of this menu item. Make sure you HTML-encode it if needed;
|
|
* - url: string|array, the URL that this item leads to. Use a string to
|
|
* represent a static URL, while an array for constructing a dynamic one.
|
|
* - pattern: array, optional. This is used to determine if the item is active.
|
|
* The first element refers to the route of the request, while the rest
|
|
* name-value pairs representing the GET parameters to be matched with.
|
|
* When the route does not contain the action part, it is treated
|
|
* as a controller ID and will match all actions of the controller.
|
|
* If pattern is not given, the url array will be used instead.
