I am still struggeling with this topic. Your recomendation to use Taxonomy Advanced instead of Taxonomy did solve the duplicate admin column issue, however it gave me new problems, since the taxonomy advanced field does not set the post terms.
I need to set the post terms, hence I switched back to Taxonomy Field and get the Problem with the Duplicate Admin Columns again.
I am really struggeling with this: How to solve this?
Hello Peter, thanks for the quick answer! Using only one taxonomy field is not applicable for me, since I need multiple Taxonomy Fields. However, I need the field to set the post term, since I want to filter it with a WP Gridbuilder facet – and since reading this Metabox Article I know that I need taxonomy to group posts together, otherwise the filtering process will be really slow.
I tried to build everything with only one taxonomy field as you suggest: With this approach it does not look good in the backend, since there is no good seperation between the different parent terms - see here: https://imgur.com/wxIzkKv
Also, and this is the bigger problem: With this approach I cannot fetch dynamic data for my Single Template, since its all in one custom field (taxonomy) rather than differerent custom fields as before (taxonomy advanced).
I think I am doing something wrong, can you please check and help me find the solution? <3
so I think I had a big misconception about this. The solution was easy: Set up several Custom Taxonomies and assign it to the same CPT. Now I select my taxonomies in the sidebar and it works as it should.
