1. Navigate to the template file for the blog you want to add the filter to (usually called "blog.liquid").
2. Add a form to the top of the file where users can select the sorting option they want. The form should have a select element with options for "featured", "old to new", "new to old", "a-z", and "z-a".
3. Add a switch case statement to the top of the loop that displays the blog posts. This switch case should check the selected option and sort the blog posts accordingly.

here is an example  

<form>
  <label for="sort-by">Sort By:</label>
  <select id="sort-by" name="sort-by">
    <option value="featured">Featured</option>
    <option value="old-new">Old to New</option>
    <option value="new-old">New to Old</option>
    <option value="a-z">A-Z</option>
    <option value="z-a">Z-A</option>
  </select>
  <input type="submit" value="Sort">
</form>

{% assign posts = blog.articles %}
{% case sort-by %}
  {% when 'featured' %}
    {% assign posts = blog.articles | where: 'featured', true %}
  {% when 'old-new' %}
    {% assign posts = blog.articles | sort: 'published_at' %}
  {% when 'new-old' %}
    {% assign posts = blog.articles | sort: 'published_at' | reverse %}
  {% when 'a-z' %}
    {% assign posts = blog.articles | sort: 'title' %}
  {% when 'z-a' %}
    {% assign posts = blog.articles | sort: 'title' | reverse %}
{% endcase %}

{% for post in posts %}
  ... code to display each blog post ...
{% endfor %}
