Support for Drupal 7 is ending on 5 January 2025—it’s time to migrate to Drupal 10! Learn about the many benefits of Drupal 10 and find migration tools in our resource center.
After a lot of wasted time I finally discovered that SHS doesn't work with entities, only nodes.
I recommend you make a note of this in the module description, or better yet, add support for entities. It's a fairly common use case, in particular as a Views exposed filter.
Hierarchical Select doesn't support exposed filters in D7 yet, although it was so slow as to be virtually unusable anyway.
