My website has a "Portfolio" Custom Repeatable Type.
A "Work" can have several tags like "visual identity", "website", "flyer"...
The listing page features a filter system (when you active a tag, all items having this tag will appear)
I thought I could create all theses tags (custom type TAGS), and use Content Relationship, but only ONE Content can be linked, so i can't link a Work to several tags.
