myForm.append(label);

Use the gui.Menu object (section 4.2.3.6) to define the menus for your application. Use the
gui.MenuItem constructor to define the controls in the menu. Each control has an
associated onClick property that defines the function of the OHV300.
The following example demonstrates how to build and display menus and submenus.
// JavaScript Menu Demo Script Document
// menu event handlers
function onTimeCard(){alert(postAlertFunc, "TimeCard");}
function onInventory()
{
gui.showSubMenu(subMenu, myMenu);
}
function onCapital(){alert(postAlertFunc, "capital");}

var myMenu = new gui.Menu();
var subMenu = new gui.Menu();
// create menu entries
var timeCardApp =
