I want to filter taxonomy terms in common to nodes related to the viewed node, but I cannot figure out how. What I am getting are all the terms that the related nodes have (with repeated terms too). Please take a look at this recipe page, side block STAG RICETTA
I am filtering seasonality terms (months) in common to ingredients nodes (the ones related to the node being viewed) used in a recipe node (the viewed one).
How can I achieve this?
