Renders a Javascript Menu based on the excellent JSCookMenu by Heng Yuan(http://www.cs.ucla.edu/~heng/JSCookMenu), the nested NavigationMenuItem(s) are rendered as Javascript Menu.
If you want to use jscookMenu in your application, you will have to:
* Add jscookmenu directory containing css and scripting code to your web directory (you can find it in the examples application).
* Add scripts and stylesheets for the theme you would like to use to html-header (see also inc/header.inc in the examples application)
* Put the tomahawk.jar in your WEB-INF/lib directory (or in the classpath of your application server.)
* Add the following to your JSP page in order to use one of the MyFaces custom components:
<%@ taglib uri="http://myfaces.apache.org/tomahawk" prefix="t" %>
Well,the syntax of jscookMenu is as follows:
<t:jscookMenu [ user-role-support-attributes ]
[layout="values {hbr, hbl, hur, hul, vbr, vbl, vur, vul}"]
[theme="values {ThemeIE, ThemeMiniBlack, ThemeOffice, ThemePanel}"]
Nested <t:navigationMenuItem> or <t:navigationMenuItems> tags (menu items)
</t:jscookMenu>
不同的 theme (效果)可以到这里查看 http://jscook.yuanheng.org/JSCookMenu/ThemeMiniBlack.html
例子：
The code in my menu.jsp is as follows:
<%@ taglib uri="http://myfaces.apache.org/extensions" prefix="x"%>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%>
<x:jscookMenu layout="vbr" theme="ThemeECCGroup" rendered="#{MenuBean.hasMenu}">
<x:navigationMenuItems value="#{MenuBean.menu}" />
</x:jscookMenu>
The code in my backing bean is as follows: (this will eventually be generated from the database)
/**
