I am building a membersite where the members can specify what their specialties are, and what services they offer and which services not.
This is implemented by a large list of services (radio buttons), and for each service 3 options:
- not offered
To avoid that a member marks everything as favorite, I want to limit the number of services that he can mark as favorite.
How to do that?
Also, I would like to maintain a counter visible on screen, so that he can see how many favorites are marked.
How would I do that?
