Select the Separator part to add a part that draws lines between menu choices on a menu. The user cannot interact with separators. The Separator part can also be used as a boundary, such as a space or a line, that provides a visual distinction between two adjacent areas.

To display the pop-up menu for the part, click with mouse button 2 on the part.

To further define the appearance and function of a part, double-click on it to open the properties window.
