Perhaps not the most accurate term. For NAMESPACES it has a submenu, so
it can't disappear as long as its selected, even if it's not editable
any more. A "leaf" level option like MULTIUSER, otoh, does disappear
completely (even though it's still selected).

But there are also things like CONFIG_VT, which stays visible, even
though its not a menu.. I think because there is a visible option that
depends on it and immediately follows, which menuconfig shows by
indenting. If the order of UNIX98_PTYS and VT_HW_CONSOLE_BINDING is
flipped in drivers/tty/Kconfig, then VT disappears when EXPERT=n.

Dunno, maybe Editable would be a better word than Visible?
