I have a custom taxonomy X.
I've specified that the UI should be shown (for debugging purposes), however the UI is now interfering with my automation. I have code that automatically mirrors terms into this taxonomy, duplicating it. Taxonomy X is effectively a copy of Taxonomy Y or a subset. This code is working almost perfectly, except that my assignment code is doing its work which is then undone by the WordPress UI code setting the terms for the post from the metabox.
So how do I make the metabox showing Taxonomy X terms read only? AKA keep the metabox, but remove any save/edit/delete hooks attached to it?
edit: for reference, if
show_ui is set to false in the registration of the taxonomy, and the UI for that tax is hidden, then everything works as expected. ( which itself is to be expected)
