Menu - mega menu does not work on mobile device

[mthor1979]

go to https://www.primefaces.org/primeng/#/megamenu on a mobile device or simply open the debugger and switch to mobile, chrome click the toggle device icon in top left of debugger. I want to use the menu, but will be forced to use the tree for I cannot use the menu on a mobile device, I have other applications that this is becoming a problem. this is not just the mega menu, any menu does not work on mobile device.
