Adds an option for a select (dropdown) display for search facets using Facet API. The select form loads by js (no need to click 'submit') but degrades to use submit button.
Install this module using the official Backdrop CMS instructions at https://backdropcms.org/guide/modules
Go to the Search index under admin/config/search/search_api which has facets
defined. On the facet click "Configure Display", change the Display Widget to
"Select field (dropdowns)" and save.
