I have seen lots of posts and plugins about being able to sort your posts/search results one way or another (i.e. alphabetical, most recent, etc.)... but I can't seem to find a solution where the user of my site can choose how they want to sort the posts (i.e. The category results for Cats could be sorted by most recent, most popular, etc.)
I have searched plugins and the forums and docs for hours and can't find a solution. Any help would be GREATLY appreciated.
