Hi Richard,
thank you very much for your answer, it's very helpful!
I'll try to check it tomorrow, but looks like teamwork graph is what I'm
looking for.
Could you tell me please, what is the best place to store some service data
that should be available for all taxonomies with possibility to manage (add
and edit) this data.
Thank you!
Best regards,
Oleksandr Mandryk
