JSF抽屉式菜单的实现

主要是使用<layout:accordionLayout/>控件实现效果，话不多说，直接上代码：

 

<f:view xmlns="http://www.w3.org/1999/xhtml" xmlns:f="http://java.sun.com/jsf/core"
	xmlns:w="http://www.apusic.com/jsf/widget" xmlns:layout="http://www.apusic.com/jsf/layout"

	xmlns:ui="http://java.sun.com/jsf/facelets" renderKitId="AJAX">
	<w:head>
		<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
		<w:stylesheet src="resources/css/style.css"></w:stylesheet>
	</w:head>
	<w:page title="Insert title here">
		<layout:borderLayout fitToBody="true">
			<layout:panel region="north" autoHeight="true" border="false">
				<ui:include src="header.xhtml"></ui:include>
			</layout:panel>
			<layout:panel region="west" width="200"  title="菜单" split="true" border="false" collapsible="true">
				<layout:accordionLayout id="layout" animate="true" fit="true" border="false"></layout:accordionLayout>
			</layout:panel>
			 <layout:panel region="center" title="center" fit="true">                
			 <w:iframe style="width: 100%; height: 100%" id="frame" src="workspace.xhtml" name="content" frameborder="no" />           
			  </layout:panel>
			  <layout:panel region="south" autoHeight="true" border="false">               
			   <ui:include src="footer.xhtml" />            
			   </layout:panel>
		</layout:borderLayout>
	</w:page>
</f:view>
