class: SplitMenuButton

[131:7] extends: MenuButton

The SplitMenuButton class wraps the JavaFX SplitMenuButton control, a hybrid control that combines a clickable action area with a separate dropdown arrow that opens a popup menu. Clicking the main area fires an action event just like a regular button, while clicking the arrow reveals a list of MenuItem choices. SplitMenuButton extends MenuButton and ButtonBase, so it inherits the armed, openvertically, and showing pseudo-classes along with the complete Labeled CSS property set. Style class: split-menu-button

CSS Pseudo-classes -- MenuButton
