After answering this, I realized it was a duplicate of JavaFX 2 custom popup pane, which has a bit more context info in some of the answers.

Use a MenuButton and in a menuItem attached to the MenuButton, set a graphic for the content you want to display in your popup.

final MenuItem wizPopup = new MenuItem();
wizPopup.setGraphic(wizBox);

final MenuButton popupButton = new MenuButton("frobozz");
popupButton.getItems().setAll(
  wizPopup            
);

Here is a complete, executable sample.
