Hi Federico @thinkaboutit, thanks for your repeated feedback on this code. Feel free to fork and tweak to your needs. The use case for this code is a client who had a list of treatments (a CPT) of various taxonomies, who needed to output them all for an overview price list. The code works perfectly for my needs (at the time of creation 4 years ago, so I do not need any additional help with this at this time, thanks! 🙏

Sorry for the comments, I wanted to note them on my github and I wrote on yours.
Thanks for your code, anyway.
bye

Thank you very much… this is the only way! easy, best man. There is so much bullshit, but this works!!!!
