Hi Ernest,
thanks for your reply but this don’t resolve my question.
I have this situation :
Taxonomy Categories -> Parent Categories Test -> Child Category TestA , TestB
Taxonomy Categories -> Parent Categories Test2 -> Child Category TestC , TestD
In the filtering settings I’ve a checkbox for categories Test and all Child Category ( I don’t show categorie Test2 ) .
If I add a new Child Categories in Test , I cannot add them dynamically but I must go in settings page and adding the new Child category in the filtering .
I have multiple search instance with different categories and I would like to populate filtering checkbox automatically with newly create Child Categories.
I hope I explained better my need, sorry for bad English language but is not my primary language .
Thanks
