that simply doesn't always work; for example I started with a minimal defconfig
and want to enable SENSORS_APPLESMC, from nconfig I can search this one
get it depends HWMON && INPUT, if the current .config doesn't have HWMON
and I just write SENSORS_APPLESMC=m there, the following rebuild will deselect
SENSORS_APPLESMC actually;
┌── Search Results ───────────────────────────────────────────────────┐

I am asking a config method that accepts a list of config items (or module names),
let it make sure all depended items also be selected?
thanks,
