the submenus sometimes go off the screen. is there something i can add to the code so that submenus stay on the screen? whatever size it is?

thank you

Hi
I don't see any submenu going out of the screen as you have activated the overflow detection, then it stay inside the menu
CEd

if the screen is reduced, it still happens

try this :
- reduce the page width
- refresh the page
- then test how it works

by my side it is ok. The fact is that if you reduce the page and do not refresh, the menu keeps the original menu item position in memory
