Adding list of nodes to another node I have a content type (named "Category") and another content type ("Article"). I want to "Category" nodes have similar functionality as taxonomy term in a way of option to assign "article" nodes to them and display list of "article" nodes teasers on the "Category" page too. 

For example: Lets say I have "Category" node named "People". And several "Article" nodes ("Joe", "Frank", "Peter") somehow (part of my question) assigned to "People". When I go to "People" page, I want to see this node content and below also teasers of all assigned "Article" nodes. And I want this not only for a specific node, but for all nodes of content type "Category". How to attain this? Maybe something like taxonomy terms view, but adapted to nodes instead of taxonomy terms?

I know it's easy with taxonomy, but I want to avoid that way - because of buggy taxonomy menu and other things. Thanks
You can use Entity Reference module to create relations between the nodes you need.

And it works well with Views (for both forward and backward references)
