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..
