For example, in the choices of newsletters for subscribers, I’d like something similar to this (note the hierarchy):
[ ] All Newsletters
[ ] All live events
[ ] in my country
[ ] in my state (U.S. only)
[ ] All online events
[ ] new courses
[ ] meet & greets
[ ] Special Announcements
If someone clicks All Newsletters, I’d like it to automatically select ALL the options below it in the hierarchy to indicate to the subscriber that they are subscribing to ALL newsletters (Special Announcements is a separate category so it wouldn’t be affected). If the subscriber then deselects new courses, it should also deselect All online events and All Newsletters but leave everything else unchanged.
Is this possible – I mean without special programming skills?
