I've created custom search terms to filter a user choice of selecting wether an event should be hidden or not.
[events_list hidden="yes"] produces a list of the events that are checked as hidden. when hidden="no" it only shows events checked as not hidden. this is fine.
[events_calendar hidden="yes"] or hidden="no" both give a calendar with all events displayed, seemingly ignoring my search filter.
I created my code by following the "creating a custom add-on" tutorial and I read that you should be able to use new search attribute in any of the event, calendar or location shortcodes. Is there something else I'm missing, something I need to add to support the use of this filter on calendars?
