Best way to show an "unactivated" part of an app?
I've got a dashboard that shows both active and unactivated parts of an app (users opt in to a service). Is there any standard for the best way to show an element/section is unactivated? Any way to encourage activation?
I'm sure there are numerous examples out there of apps that have "can't use this till you pay" section, but I can't seem to find anything that would illuminate a standard practice here.
Thanks!
