- * page displayed. In particular, a menu item is considered as active if

- * the URL it represents is for the page currently displayed.

- *

- * Usage of XListMenu is similar to PRADO list controls. Each list item has

- * two extra properties: {@link XListMenuItem::setPagePath PagePath} and

- * {@link XListMenuItem::setNavigateUrl NavigateUrl}. The former is used to

- * determine if the item is active or not, while the latter specifies the

- * URL for the item. If the latter is not specified, a URL to the page is

- * generated automatically.

- *

- * In template, you may use the following tags to specify a menu:

- * <code>

- *   <com:XListMenu ActiveCssClass="class1" InactiveCssClass="class2">

- *      <com:XListMenuItem Text="Menu 1" PagePath="Page1" />
