is there anyway to split a pie menu item into 2 buttons, for example box.operator, as seen in some of wazou’s pie menus? i know it can be done by creating a separate popup dialog but creating one just for 2 buttons seems inefficient tbh.
Yes, you can use Custom tab:
box = L.box(); col = box.column(True); col.operator("object.shade_smooth"); col.operator("object.shade_flat")
