title: Sitecore SXA Search Dropdown Filter
body: <p>I have been tasked with building a search page for our site with OOB Sitecore search components.  One of the things I need to do is to filter by a custom list of items.  This items will be mapped to the template name (guid).  So for example I want to add 'Article', 'Page', 'Document' or something like that to the dropdown filter, and then if 'Article' is chosen, filter to show only the items that are based on an Article template (which might be called something like 'Blog Article').</p>
  <p>In Sitecore I've built most of the search except for this dropdown.  How would I go about doing something like this?  It seems like I could create the 'Article', 'Page', 'Document' as items in Sitecore and then use a query to populate the dropdown.  Am I on the right track?</p>
