Build a new menu by creating a new Menu object and then working on it in the Menu painter.
To create a new menu:
The Menu painter opens and displays the Tree Menu view and the WYSIWYG view for defining the menu, and the General, Appearance and Toolbar categories in the Properties view for setting menu and toolbar properties.
Because you are creating a new menu and have not added menu items yet, the only content is an untitled top-level tree view item in the TreeMenu view.
