ToolStripDropDownMenu is the base class for ContextMenuStrip, providing necessary painting and layout properties and methods. The properties of this class that you are most likely to use directly are the ShowCheckMargin and ShowImageMargin properties, which determine whether the shortcut menu will be able to display a check mark, an image, or both.

The following code example demonstrates how to create and initialize a ContextMenuStrip control by setting the check and image margins.
