public class MenuButton extends ButtonBase
MenuButton is a button which, when clicked or pressed, will show a `ContextMenu`. A MenuButton shares a very similar API to the `Menu` control, insofar that you set the items that should be shown in the `items` ObservableList, and there is a `text` property to specify the label shown within the MenuButton.

As mentioned, like the Menu API itself, you'll find an `items` ObservableList within which you can provide anything that extends from `MenuItem`. There are several useful subclasses of `MenuItem` including `RadioMenuItem`, `CheckMenuItem`, `Menu`, `SeparatorMenuItem` and `CustomMenuItem`.

A MenuButton can be set to show its menu on any side of the button. This is specified using the `popupSide` property. By default the menu appears below the button. However, regardless of the popupSide specified, if there is not enough room, the `ContextMenu` will be smartly repositioned, most probably to be on the opposite side of the MenuButton.

Example:

     MenuButton m = new MenuButton("Eats");
     m.getItems().addAll(new MenuItem("Burger"), new MenuItem("Hot Dog"));

MnemonicParsing is enabled by default for MenuButton.
