Hi i have created a tree using struts dojo plugin

   
<d:treenode id="DataSource" label="DataSource">
		<d:treenode id="create_datasource" label="<b>Create DataSource</b>" onclick="testAlert();" />
		<d:treenode id="edit_datasource" label="<b>Edit DataSource</b>" />
		<d:treenode id="list_datasource" label="<b>List DataSource</b>" />
	</d:treenode>
