How to correctly override taxonomy category field in admin?

1

Created blueprint under: “themes/MYTHEME/blueprints/single-news.yaml”

title: News
'@extends':
    type: default
    context: blueprints://pages

form:
  fields:
    tabs:
      type: tabs
      active: 1

      fields:
        
        options:
          type: tab

          fields:

            taxonomies:

              fields:

                header.taxonomy.category:
                  validate:
                    required: true

It doesn’t work. I also checked admin plugin repo source codes and couldn’t find anything regards on how the fields are named in yaml, in order to override/extend them.

you can check for original blueprints in system/src/blueprints

Ok, found it:

            taxonomies:
              type: section
              title: PLUGIN_ADMIN.TAXONOMIES
              underline: true

              fields:
                header.taxonomy:
                  type: taxonomy
                  label: PLUGIN_ADMIN.TAXONOMY
                  multiple: true
                  validate:
                    type: array

What’s the correct way to override in my blueprint? Just copy everything and add my validation?
