Hello
Dont know if this is possible but would be reall cool to implement on k2.
Something like wordpress does:
justintadlock.com/archives/2009/05/06/custom-taxonomies-in-wordpress-28
Tags can be translated and are user friendly, the searchable extra items not.
Righ now we have:
Product Name
Tagged under: blue, big, cheap, leather
If we could have multiple tag types and could translate tag to whatever we like we could have something like this:
Product name
Color: Blue
Size: Big
Price Range: Cheap
Material: Leather
Tags are very powerfull and will be great type of extra field,
We could make a menu item by tag type, translate the tags, etc
