Setting up something for a client where the taxonomy may frequently update. Have seen some situations where changing the items in a select field (I think) meant that all previous posts using that field had to be re-saved when a new value is added later. That would be a disaster in this case.
So I’m curious what might be the most flexible field when new selections get added?
Or would it be better to use a custom taxonomy in combo with radio buttons? Fairly flexible in terms of the interface, but requires stability so that when they add new categories, no previous posts would be affected.
