Taxonomy vs. taxonomy advanced

Hello,

The difference between taxonomy and taxonomy_advanced fields is noted in the documentation
https://docs.metabox.io/fields/taxonomy-advanced/

- taxonomy: set the post terms, data is stored in the table wp_terms
- taxonomy_advanced: set the post meta, data is stored in the table wp_postmeta, like other custom fields

you can also follow this article https://metabox.io/custom-fields-vs-custom-taxonomies/
to know when using a custom field or custom taxonomy.

Hello,

>> Can you provide use cases why someone would use taxonomy_advanced over taxonomy?

In some cases, you have to use the taxonomy_advanced field: subfield in a group or field in a block. Because the taxonomy set post terms so it won't work in those cases.

Besides that, when you want to save the field value as post meta instead of post term, you will use the field taxonomy_advanced.
