Remove arrow on JavaFX menuButton

Question

Hi JavaFX Stylesheet expert,

How do I remove the default arrow on JavaFX menuButton.

I have figured how to change the color and make in unvisible with

.menu-button {
    -fx-mark-color: transparent;
}

or

.menu-button .arrow {
    -fx-background-color: transparent;
}

but, I don't want the gap because of the unvisible arrow.

Thanks for your advice.

Best Regards,

Ivan

If we look into the source code of MenuButtonSkinBase, the sub structure of MenuButton seems to be

MenuButton
   |——— label (LabeledImpl)
   |——— arrowButton (StackPane)
            |——— arrow (StackPane)

So to hide the "arrow" it is enough to set padding to 0 for both StackPanes:

.menu-button > .arrow-button {
    -fx-padding: 0;
}

.menu-button > .arrow-button > .arrow {
    -fx-padding: 0;
}
