Context
Currently using facets to provide a hierarchical select filter.
You have to select a top level item, then the filter updates with the children.
This can be confusing.
Questions
Can we add additional dropdowns when each level is selected?
Can we have a list of links for the top level?
With dependent facets, can I move them to a second row of filters, so they don't move them when expanded?
Discovery
New commits in Facets 3.x adds support for dependent facets.
Need a way to place the facets so the dependent facets that get added as you make selections don't move other filters around.
Issues
