I’ve created a view called “Upcoming Events” that presents upcoming events in chronological order at the url /upcoming-events/all. Each event has associated tags. Currently my contextual filter is set so that replacing all in the url with a valid tag will present just events with that tag. Tags are set up as links with the url /upcoming-events/[field_tags].
My question is two-fold. How do I set up the contextual filter so that adding more tags on the end of the url (/upcoming-events/happy-hours/drupal/ for example) will further narrow the results presented to the user? Also, how do I set up the tag links to append the field tag to the end of the url rather than replace it?
