To add a flyout toolbar button to a toolbar, use the AddToolbarButton method. This method creates a new ToolbarItem object and adds it to the designated toolbar.
The AddToolbarButton method takes five parameters as input: Index, Name, HelpString, Macro, and FlyoutButton. By setting the FlyoutButton parameter to TRUE, the new button will be created as a flyout button. The return value from this method will be the new flyout toolbar. The flyout toolbar can then be populated as a normal toolbar would be.
This example creates two toolbars. The first toolbar contains a flyout button. The second toolbar is attached to the flyout button on the first toolbar.
