Delphi/Lazarus: Show Separator Line in Menu

Indeed, there is not a real "option" for this available, you just have to know the trick:

For creating a separator line, you have to set the caption of the corresponding menu item to "-". As soon as the caption is only consisting of a hyphen, when starting the application, a menu divider is created thereof.

MenuItem1.Caption := 'Item before Divider';
MenuItem2.Caption := '-';
MenuItem3.Caption := 'Item after Divider';

Here is a small example showing this behavior: MenuItem2 is becoming the separator, the items before and after are displayed with their normal caption.
