How to knit posts in joomla 3 and display in the module of a specific post?

Question

PHP

Good afternoon. There is joomla 3 and component k2.
There are two sections: Goods (k2) and News. When adding news, you need to specify in which product this news should be shown. Maybe somehow through the tags you can connect? Tell me please. News can also be filled in in k2 or in the usual Joomla component of articles, the main thing is that it works.

Answer 1

The most "ugly", but technically simple way - put something like articlesanywhere from nonumber
Alternatives - write the code yourself
