i'm new to drupal (just installed v9) and want to add a bunch of content. like in the question asked years ago (Create taxonomy terms on the fly) i want to add taxonomy terms on the fly while adding new content and not having to add them first in the taxonomy module.
the links provided in the old thread are for v7 and v8 and seem not to work
if the code thats posted there is still a valid solution can one tell me where to add it? thanks
