I have a client that is looking to have an archive list by blog (easy) but what isn't so easy is that they also want a Categories List next to it where as each blog post in a blog instance has one of 7 categories associated with it and the blogposts
would be filtered by it.
Obviously it's very easy to add a enum to a blog post but how would I go about creating a module that would (like archive widget) allow me to chose a blog it points at, list the 7 categories and ultimately when clicked, filter to only show the
blog posts meeting that criteria?
I'm in Orchard 1.4. I'm thinking projections somehow but frankly I haven't taken the time to dig into them yet.
