No doubt metabox io saved a lot of time but I need your help here badly. I have a taxonomy which I don't want to show up on post screen but want to show in a group once certain key is selected. I am doing it right and my field is showing as well.
But once I save the field it did not set to my post as taxonomy but saved in the post meta. How can I do that with taxonomy field ? As documentation states that I should be able to do it but what's causing it to not save, I copied code from your taxonomy page and taxonomy field is showing fine.
Only issue is its saving to meta box table not setting as post terms.
