Mutlti level filter with search api and facet in commerce kickstart

Question

I'm using commerce kickstart, I want to use the built-in filter blocks (facet & search-api).
I have multi-level categories (taxonomy), but filters just display parents categories.
For example I have as categories:

computers
-laptops
-desktops
-notebook
Networking
-routers
-modems

Filters just display computers and networking

Answer 1

It sounds like you need to enable the "Expand Heierarcy" option under Facet Display settings (for the search index you are working with).
