ability to select from a list of available tags - dropdown search or similar - django admin

[Jihad]

Spent couple of hours finding a good solution for this, the closest is this:
https://stackoverflow.com/questions/48086513/django-taggit-display-existing-tags-on-the-django-admin-add-record-page

using an old django-taggit-autosuggest.

My case is:
I have multiple type of tags, like: Skills, theme, music types..etc
each one can have up-to 20 tags.

I want by when creating new "post" to be able to select from the existing, rather than adding comma separated ones which might cause duplication issues and forgetting about some, is not practical.

If there is a missing tag to be added, it's fine to create it manually first from the taggit/tags page, then select it from the post create/edit page.

What is the recommended approach for this?
