Hi,
What i want to know is, is there a module/component that i can put tags on articles/items, categories from K2 and when lets say they click on a category or article to open it shows a module on side that shows a list of all possible articles that have same tags as the one opened.

So something like "related articles module" that works with K2 component as well

Thanks :)

Hello Antonio,

The functionality you want is built in by default with the K2 item, you can adjust it's settings from the category options.
