Here it is, using a Popup: https://github.com/TomasMikula/jfxtras-labs/blob/8.0/src/main/java/jfxtras/labs/scene/menu/CirclePopupMenu2.java https://github.com/TomasMikula/jfxtras-labs/blob/8.0/src/main/java/jfxtras/labs/scene/menu/Sample2.java
The nice thing about popup window is that it can extend beyond the bounds of the owner window. Just let me know if transparency works for you as expected. Some time ago transparency stopped working on my system and I didn't care to find out why, so my Popup has white background instead of transparent, but should be transparent on a healthy system.
