If you are doing basic WordPress site you are sure going to come to a need for displaying your posts by certain tags or categories. Collectively these are called taxonomies, they are a way for you to categorize your site into some logical parts.

In this episode we are going to learn how you can display posts that belong to certain categories, tags or even how to display posts that don't belong into those taxonomies.

For this we are going to be using `cat`, `tag`, `category__in`, `tag__not_in` and similar properties that `WP_Query` object provides for us.

In this WordPress Custom Query tutorials we are going to tackle displaying our posts by filtering them with tags and categories.

Taxonomy

In Middleman they are called "Custom Article Collections" and they can be any kind of taxonomy you want. Also they are a bit limited and not as advanced like in WordPress or Drupal. But if you combine them with tags you should be OK.

In this episode of Building Web Sites With Middleman Static Site Generator we are going to take a look at categories.

Middleman Categories

As I wasn't able to do anything for this tutorial by following official Middleman documentation, so I had to find some round about ways to learn how to do what I wanted. In this tutorial I'm going to walk you through that process.

We are going to learn how to display list of all tags for our blog, and also how to display tags for every post we have.

Middleman static site generator has some great documentation, but some of it is not that good. Tags are not explained very well, especially if you have multiple Middleman blogs.
