LinkChoice 

A LinkChoice is a button that offers various options through a triangle symbol.

If the user clicks on the triangle symbol, a menu opens from which an action can be selected. A specific action is executed when the user selects the relevant menu entry.

A LinkChoice functions exactly like a ToolBarLinkChoice, but it is used differently - LinkChoice can be used outside of a ToolBar.
