The PopUpButton control adds a flexible pop-up control interface to a Button control. It contains a main button and a secondary button, called the pop-up button, which pops up any UIComponent object when a user clicks the pop-up button.
A PopUpButton control can have a text label, an icon, or both on its face. When a user clicks the main part of the PopUpButton control, it dispatches a click event.
