Popup Windows: menubar

The menu bar is the menu for the popup window. By default popups don't have menu bars. You can configure the popup to have a menu by setting menubar to yes in the open() command. So, for example, this open() command in the popup script configures the popup to have a menu bar:

window.open(href, windowname, 'width=400,height=150,menubar=yes,scrollbars=yes');

which gives us this popup.
