It is.
Now is there some way to not have to duplicate the 'config choices
between if ONLY_HAVE_ONE and if !ONLY_HAVE_ONE
To use your example I want to do:
config ONLY_HAVE_ONE
prompt "only have one?"
boolean
if ONLY_HAVE_ONE
config VAL_FIRST
bool "First value"
config VAL_SECOND
bool "Second value"
endif
if !ONLY_HAVE_ONE
choice
prompt "multiple values"
default VAL_FIRST
config VAL_FIRST
bool "First value"
config VAL_SECOND
bool "Second value"
endchoice
endif
I'd like not to have to repeat/duplicate VAL_FIRST, VAL_SECOND, etc..
