Cascade menu even if clicked on button (but not arrow)?

I dont remember how but I made it work that way before - it was very useful on touch screen (tablet).
After I reinstalled everything I cant find it in settings… Was it removed?

Hello - if the top level button does ot have any command string at all, it will immediately cascade the linked toolbar.


Is it possible to apply this to all cascadable buttons at once? It used to work on all buttons like that.
