I love the extra fields the way I currently understand it. It allows me to attach unified information to items throughout a category.

But do they do more than than that? Can we filter articles by Extra fields? Or show other articles with the same value for an extra field? Or are they used or something else other than just showing information?

Hi Benjamin! Module placed on joomcar.net may filter your K2 content by several extra fields at the same time. Try it!
