To create an context menu in Tree element i used the following code.
TreeViewer viewer=new TreeViewer();
final MenuManager mgr = new MenuManager();
mgr.setRemoveAllWhenShown(true);
Action action1=new Action();
Action action2=new Action();
mgr.addMenuListener(new IMenuListener() {
public void menuAboutToShow(IMenuManager manager) {
IStructuredSelection selection = (IStructuredSelection) viewer
getSelection();
if (!selection.isEmpty()) {
action1.setText("Add");
action2.setText("Append");
manager.add(action1);
manager.add(Action2);

}
}
});

Now i am getting the context menu when i right click on the tree elements.
But i want to create submenu, so tell me how to create submenu while clicking on Add/Append action in context menu.

Thanks,
Joe

MenuManager subMenu = new MenuManager("Sub");
subMenu.add(new Action() { ... whatever ... });

In your about to show, create a MenuManager for your submenu and then
add other actions to it.
