2、jsp文件
2.1、导入两个标签库
<%@taglib prefix="s" uri="/struts-tags"%> <%@taglib prefix="sd" uri="/struts-dojo-tags"%>
2.2在jsp的head中加入属性：
<head> .... <s:head theme="xhtml" /> <sd:head parseContent="true" /> </head>
2.3、添加tree
<sd:tree id="root" label="操作选项" showGrid="true" showRootGrid="true" toggle="explode" treeSelectedTopic="test"> <sd:treenode id="child1" label="查看信息" /> <sd:treenode id="child2" label="我的班级"> <sd:treenode id="subchild1" label="共享信息" /> <sd:treenode id="subchild2" label="班级公告" /> </sd:treenode> </sd:tree>
