The MenuButton control is a button that, when clicked, does not perform any action other than show/hide a menu containing menu items. For this reason, unlike the normal JavaFX Button control, there is no action property that you can define.

MenuButton

When users click on MenuButton, a menu will be displayed, the menu's Items can be MunuItem, CheckMenuItem, RadioMenuItem or SeparatorMenuItem. And you can handle events when users click on the items, basically there is no difference between MenuButton and a normal Menu.

SplitMenuButton

MenuButton vs SplitMenuButton.

SplitMenuButton very similar to a MenuButton, and it is the same as a Button, it allows you to mount an action when the user clicks on the left. Note SplitMenuButton divided into two parts left and right. When the user clicks on the left it act like a Button, when users click on the right side it acts like a MenuButton.
