+/**
+ * AdwSplitButton:
+ *
+ * A combined button and dropdown widget.
+ *
+ * `AdwSplitButton` is typically used to present a set of actions in a menu,
+ * but allow access to one of them with a single click.
+ *
+ * The API is very similar to [class@Gtk.Button] and [class@Gtk.MenuButton], see
+ * their documentation for details.
+ *
+ * ## CSS nodes
+ *
+ * ```
+ * splitbutton[.image-button][.text-button]
+ * ├── button
+ * │ ╰── <content>
+ * ├── separator
+ * ╰── menubutton
+ * ╰── button.toggle
+ * ╰── arrow
+ * ```
+ *
+ * `AdwSplitButton`'s CSS node is called `splitbutton`. It contains the css
+ * nodes: `button`, `separator`, `menubutton`. See [class@Gtk.MenuButton]
+ * documentation for the `menubutton` contents.
+ *
+ * The main CSS node will contain the `.image-button` or `.text-button` style
+ * classes matching the button contents. The nested button nodes will never
+ * contain them.
+ *
+ * ## Accessibility
+ *
+ * `AdwSplitButton` uses the `GTK_ACCESSIBLE_ROLE_BUTTON` role.
+ *
+ * Since: 1.0
