What is involved in filtering the Recent Posts by category according to what page you are on? My business provides commercial services and residential services. I have Recent Posts showing in the sidebar, but the commercial clients will have no interest in seeing residential service posts and visa versa. Is there some way to make it such that the Posts listed are filtered (by category) so that depending on what page you are on, only posts from specific categories are listed? I searched for plugins, but didn't find any. Or do I need to make custom page templates? Thanks for any help.
