Setup for menu and sub menu:
mob/proc
make_menus()
winset(src, "Menu", "parent=menu;name=Menu")
winset(src, "forums", "parent=Menu;name=Forums;command=Forums")
winset(src, "hub", "parent=Menu;name=HUB;command=HUB")
hide_menus()
winshow(src, "Menu", 0) //none of these worked
winshow(src, "menu.Menu", 0)
winset(src, "Menu", "is-visible=false")
winset(src, "menu.Menu", "is-visible=false")
winset(src, null, "menu.Menu.is-visible = false")
where menu.Menu is the name of the window followed by the name of the actual element you wish to hide.
