## org.apache.struts2.dojo.components
Class TreeNode

    java.lang.Object
      org.apache.struts2.components.Component
          org.apache.struts2.components.UIBean
              org.apache.struts2.components.ClosingUIBean
                  org.apache.struts2.dojo.components.TreeNode

    public class TreeNode

extends ClosingUIBean

Renders a tree node within a tree widget with AJAX support.

Either of the following combinations should be used depending on if the tree is to be constructed dynamically or statically.

Dynamically:

- id - id of this tree node
- title - label to be displayed for this tree node

Statically:

- rootNode - the parent node of which this tree is derived from
- nodeIdProperty - property to obtained this current tree node's id
- nodeTitleProperty - property to obtained this current tree node's title
- childCollectionProperty - property that returnds this current tree node's children

Examples

     <-- Creating tree statically using hard-coded data. -->
     <s:tree id="..." label="...">
        <s:treenode id="..." label="..." />
        <s:treenode id="..." label="...">
            <s:treenode id="..." label="..." />
            <s:treenode id="..." label="..." />
        </s:treenode>
        <s:treenode id="..." label="..." />
     </s:tree>

     <-- Creating tree dynamically using data from backing action. -->
     <s:tree
              id="..."
              rootNode="..."
              nodeIdProperty="..."
              nodeTitleProperty="..."
              childCollectionProperty="..." />
