Is that true? At the same time taxonomy_advanced fields are clonable, but I can't set taxonomies to the posts with these. I also noticed that someone here had made a workaround code (save_post) but I can't get it from the Pastebin anymore.
PS. I use older MB Builder version since the newest one doesn't work with the hierarchical taxonomies at all.
Yes, it's true. Taxonomy field when saving will set the post terms. So, it can't be cloned. Only the taxonomy advanced field, where the term IDs are saved, can be cloned.
OK, but can you tell me how to solve the problem if I have a hierarchical taxonomy field with select tree and I want to set several terms (together with the children) to the post?
