Widget with nested radial (“pie”, “flower”) menu. No WYSIWYG by now, but the menu is easily defined by self-explanatory JSON, by blueprints and in C++ (and any mixture of the above).

Each “leaf” has its title, icon and action.

Each leaf may serve as a submenu as well, then the click will open new “pie” and so on and so forth. You can “hardcode” a widget or deploy at runtime.

Customizable colors, rotation, custom icons for each menu item, custom menu proportions. Take any action upon menu click – events are exposed to both blueprint and C++.

Two modes of interactions are always available: obvious click-click-click and faster “click-drag-release”.



  • One draw call per pie menu, extremly performant
  • Precise segment click detection
  • Unlimited menu nesting. Each new level is positioned automatically
  • Two modes of operation - click-click-click and click-drag-release
  • All the complex logic is optimized in C++
  • Each event includes the whole history of clicks (i.e., if user clicks 3-lvl deep menu “Huge” you will know that he clicked “Deploy”, then “Bomb” and, finally, “Huge”.
  • Similarly-looking basic round button to be used alongside a menu
  • CSS-like styling, one asset to change look for many menus
