I use Gantry Framework to display widgets contextually based on various parameters (page, category, tag, etc)
Events Cal Pro lists creates a few options in that manner (event category, venue, organizer, etc) but does not seem to create a way to display contextualized widgets on the calendar pages itself. In my case at /events.
At it’s most basic I would like to create links for the calendar to display the categories therein…trying to use a text widget to do that, it just won’t display.
