GalleryDropDown is one of the DevExpress controls that provide the gallery functionality. General information on galleries, items and gallery initialization can be found in the following topics:
The control's gallery can be accessed with the GalleryDropDown.Gallery property, which is of the InDropDownGallery class (a BaseGallery descendant). To initialize a gallery, first add gallery groups to the BaseGallery.Groups collection. Then, add gallery items to each group using the GalleryItemGroup.Items collection.

- Capability to display additional commands (bar item links) below the gallery (see PopupMenuBase.ItemLinks).
