Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public class ToolStripDropDownButton extends ToolStripDropDownItem

ToolStripDropDownButton looks like ToolStripButton, but it shows a drop-down area when the user clicks it. Hide or show the drop-down arrow by setting the ShowDropDownArrow property. ToolStripDropDownButton hosts a ToolStripOverflowButton that displays items that overflow the ToolStrip.

Use the ToolStripDropDownButton to activate familiar drop-down controls such as color pickers. Set the ShowDropDownArrow property to true to more clearly indicate to the user that further options are available on the drop-down list.

The following code example displays three ToolStripButton controls when the ToolStripDropDownButton is clicked. The buttons change the foreground color of the form.
