I am currently migrating from Drupal 6 to Drupal 8, and we do not find the contributed module "Hierarchical Select" available, and I would ask if anyone knows an alternative module in Drupal 8 offering similar functionality.
Thank you in advance for the help/guidance you can lend me.
Upgrading already? wow, ambitious.
Anyway..
The Client-side hierarchical select module seems to have a Drupal 8 branch and is the only hierarchy select module I can find that does.
I think it is superior too as afaik it does not require ajax requests.
