Remarks
A RibbonDropDown can contain RibbonDropDownItem objects and RibbonButton controls.
You can create a RibbonDropDown at run time by using the CreateRibbonDropDown method of the RibbonFactory object.
There are two ways to access the RibbonFactory object:
By using the Factory property of the Ribbon class. Use this approach from code in your Ribbon class.
By using the Globals.Factory.GetRibbonFactory method. Use this approach from code outside your Ribbon class.
You cannot add buttons to the Buttons collection at run time after the Ribbon has been loaded into Office.
The procedures below explain how to add RibbonDropDownItem objects and RibbonButton controls to a RibbonDropDown.
To add RibbonDropDownItem objects at design time
Click the Items property in the Properties window.
Click the ellipsis (...).
In the DropDown Collection Editor, add, order, and edit new items.
You can add RibbonButton controls to a RibbonDropDown at design time.
To add RibbonButton controls at design time
Click the Buttons property in the Properties window.
Click the ellipsis (...).
In the Button Collection Editor, add, order, and edit new button controls.
Some members of this type can be set only before the Ribbon is loaded into the Office application. For information about setting these properties, see Ribbon Object Model Overview.
