At the time there is a difference between the facet filters in a Space and the facet filters in Products. The main difference being that in a Space you are able to collapse a filter and in Products you are not. Since the configuration XML for all these filters are the same, this is rather confusing.
I would like to propose to make this behavior of collapsing facets configurable in the XML so you are able to create the same experience.
