The original function is old. Its actually better to check $params['depth']
rather than lookup the term's parents with get_ancestors. See example - https://gist.facetwp.com/gist/gist-89af85b742c856aa2b3f193e019edd5b/

@chekle Thank you very much!
It's so strange. I can see that the script is linked correctly to my facet, but the thing is that after reindexing nothing is when
if ( count( $parents ) !== 0 )
is not 0. My understanding is that when I set it to 1 the parent and only one child level is shown.My list looks like this:
I would like expand the parent and child, all second children should be collapsed.
Update: Ok, I think – even though I couldn't get the script work correctly – that this isn't the script I was looking for. It skips rows from indexing instead of collapsing it. I'm continuing my search :)
