/**
|
|
|
15 |
* XListMenu class
|
|
|
16 |
*
|
|
|
17 |
* XListMenu displays a list of hyperlinks that can be used for page menus.
|
|
|
18 |
* Menu items adjust their css class automatically according to the current
|
|
|
19 |
* page displayed. In particular, a menu item is considered as active if
|
|
|
20 |
* the URL it represents is for the page currently displayed.
|
|
|
21 |
*
|
|
|
22 |
* Usage of XListMenu is similar to PRADO list controls. Each list item has
|
|
|
23 |
* two extra properties: {@link XListMenuItem::setPagePath PagePath} and
|
|
|
24 |
* {@link XListMenuItem::setNavigateUrl NavigateUrl}. The former is used to
|
|
|
25 |
* determine if the item is active or not, while the latter specifies the
|
|
|
26 |
* URL for the item. If the latter is not specified, a URL to the page is
|
|
|
27 |
* generated automatically.
|
|
|
28 |
*
|
|
|
29 |
* In template, you may use the following tags to specify a menu:
|
|
|
30 |
* <code>
|
|
|
31 |
* <com:XListMenu ActiveCssClass="class1" InactiveCssClass="class2">
|
|
|
32 |
* <com:XListMenuItem Text="Menu 1" PagePath="Page1" />
|
|
|
33 |
* <com:XListMenuItem Text="Menu 2" PagePath="Page2" NavigateUrl="/page2" />
|
|
|
34 |
* </com:XListMenu>
|
|
|
35 |
* </code>
