I'm using Gmap Views to show where each Eastern Star Chapter in Maine is, both extant and historical. The automatic Node Locations map in the Navigation menu is displaying them correctly so far. What I would like to do is filter this so only nodes of type "chapter" are displayed, and preferably only ones marked as "active", although I won't generally have an exact geocode for the inactive ones. Thanks!
(This is very similar to a question I asked before, but it didn't get much input, so I'm asking it a different way this time.)
