    <p>I need to implement a content tree with context menu (add, delete, edit) in JSF 2.0. Please suggest me some components. The tree node should be an object like (Data, ID). When I click on tree node I need to get the id to backend bean.</p> <p>Example:</p> <h1>index.xhtml</h1> <p> Prime Tree </p> <pre><code> &lt;p:growl id="messages" showDetail="true" /&gt; &lt;p:tree value="#{treeBean.root}" var="node" id="pTree" selectionMode="single" selection="#{treeBean.selectedNode}"&gt; &lt;p:treeNode&gt; &lt;h:outputText value="#{node}" /&gt; &lt;/p:treeNode&gt; &lt;/p:tree&gt; &lt;p:contextMenu for="pTree" id="cmenu"&gt; &lt;p:menuitem value="Add topic as child" update="pTree, cmenu" actionListener="#{treeBean.addChildNode}" /&gt; &lt;p:menuitem value="Add topic Below" update="pTree, cmenu" actionListener="#{treeBean.addTopicBelow}" /&gt; &lt;p:menuitem value="Delete Topic" update="pTree, cmenu" actionListener="#{treeBean.deleteNode}" /&gt; &lt;/p:contextMenu&gt; &lt;/h:form&gt; &lt;/h:body&gt; </code></pre> <p></p> <h1>TreeBean.java</h1> <p>/* * To change this template, choose Tools | Templates * and open the template in the editor. */</p> <p>package com.prime.tree;</p> <p>import java.io.Serializable; import javax.faces.application.FacesMessage; import javax.faces.bean.ManagedBean; import javax.faces.bean.SessionScoped; import javax.faces.context.FacesContext; import javax.faces.event.ActionEvent; import org.primefaces.model.DefaultTreeNode; import org.primefaces.model.TreeNode;</p> <p>/** * * @author Veerendra */ @ManagedBean @SessionScoped public class TreeBean implements Serializable {</p> <pre><code>private TreeNode root; private TreeNode selectedNode; public TreeBean() { root = new DefaultTreeNode("Root", null); List rootNodes&lt;Employee&gt; = SearchDao.getRootNodes(); Iterator it = rootNodes.iterator(); while (it.hasNext()) { TreeNode node1 = new DefaultTreeNode(**it.next()**, root); **/* in place of it.next() I need to display empName. When I click on empName, I need to get the Id(Pkey). */** } } public TreeNode getRoot() { return root; } public TreeNode getSelectedNode() { return selectedNode; } public void setSelectedNode(TreeNode selectedNode) { this.selectedNode = selectedNode; } public void addChildNode(ActionEvent actionEvent) { System.out.println("Selected Node: "+getSelectedNode().toString()); TreeNode newNode = new DefaultTreeNode("Node New", getSelectedNode()); getSelectedNode().setExpanded(true); } public void addTopicBelow(ActionEvent actionEvent){ TreeNode newNode = new DefaultTreeNode("Node New", getSelectedNode().getParent()); } public void deleteNode(ActionEvent actionEvent){ System.out.println("Node to be deleted: "+getSelectedNode().toString()); //getSelectedNode(). } </code></pre> <p>}</p> <h1>Employee.java</h1> <p>public class Employee{</p> <pre><code>private String empID; private String empName; /** * @return the empName */ public String getEmpName() { return empName; } /** * @param empName the empName to set */ public void setEmpName(String empName) { this.empName = empName; } /** * @return the empID */ public String getEmpID() { return empID; } /** * @param empID the empID to set */ public void setEmpID(String empID) { this.empID = empID; } </code></pre> <p>}</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
