{% assign level = 0 %}
{% assign previous_level = 1 %}
{% assign sorted_pages = site.pages | sort:'url' %}
{% for page in sorted_pages %}
  {% assign level = page.dir | split:"/" | size | minus:1 %}
  {% if level > previous_level %}
    <ul>
  {% elsif level < previous_level %}
    </ul>
  {% endif %}
  <li><a href="{{page.url}}">{{page.dir | split:"/" | last | replace:'-',' ' }}</a></li>
  {% assign previous_level = level %}

{% endfor %}
