Currently, we allow users to create new tax categories and those categories basically consist of a name. In the database model, though, we support an external reference code.
We simply need to allow administrators to manage this external reference code in the UI.
- Allow users to manage the external reference code for a tax category.
- Add to the mocks for the new admin UI which hasn't been implemented
- Add a mock for the old admin UI patterns
- If you've forgotten where tax categories are, they're managed at Control Panel → Commerce → Settings → Tax Categories
