Menu option under recursive tree item/folder & checkbox in tree

Question

Hi,
I want to present a checkbox next to an item or folder in a recursive tree.
I didn't see any option to do it so I tried to add a menu and a menu option type checkbox under the node item and note type.
The issue it does nothing.
Any ideas?
THanks,
Itay

Hi Akshay,
Everything mentioned here step by step:
0. You cannot use check-boxes inside tree, so you have to emulate them with images (or use Table with Tree-like master column -- not discussed in this message)
1. Create boolean attribute <b>isChecked</b> in node
2. Create calculated read-only string attribute cbIcon, write following in generated getter function:
return element.getIsChecked() ?
  "~sapicons/b_okay.gif" : "~sapicons/b_canc.gif";
or whatever images you are using.
3. Create & bind action onAction for TreeNode / TreeItem.
  -- apply parameters mapping in wdDoModifyView:
if ( firstTime )
  final IWDTreeNodeType treeNode = (IWDTreeNodeType)
    view.getElement("<your-tree-node-element-id>");
  treeNode.mappingOfOnAction()
    .addSourceMapping("path", "selectedElement");
  <b>Your action must define parameter with type of your node element and name <i>selectedElement</i></b>
  -- write the following code for handler:
selectedElement.setIsSelected( !selectedElement.getIsSelected() );
4. Bind cbIcon attribute as TreeNode / TreeItem image source, bind rest of attributes.
--Done.
