instructions.md

How do enable sub menus in the Minimal theme

1. Replace the site-nav.liquid snippet with the one below.
2. Add the css below to the bottom of styles.scss.liquid
3. If you haven't already, create your sub linklists by folowing the same procedure as mentioned in this doc
4. Result:

site-nav.liquid

<ul class="horizontal unstyled clearfix {% if settings.navigation_alignment == "right" %}fr{% endif %}">
  {% for link in linklists.main-menu.links %}
  {% assign child_list_handle = link.title | handle %}
  {% if linklists[child_list_handle] and linklists[child_list_handle].links.size > 0 %}
  <li class="dropdown">
    <a href="{{ link.url }}" {% if link.active %} class="current"{% endif %}>
      {{ link.title }}
      <i class="fa fa-angle-down"></i>
    </a> 
    <ul class="dropdown">
      {% for child_link in linklists[child_list_handle].links %}
      {% assign grand_child_list_handle = child_link.title | handle %}
      {% if linklists[grand_child_list_handle] and linklists[grand_child_list_handle].links.size > 0 %}
      <li class="dropdown">
        <a href="{{ child_link.url }}" {% if child_link.active %} class="current"{% endif %}>
          {{ child_link.title }}
          <i class="fa fa-angle-right"></i>
        </a>
        <ul class="dropdown">
          {% for grand_child_link in linklists[grand_child_list_handle].links %}
          <li>
            {{ grand_child_link.title | link_to: grand_child_link.url }}
          </li>
          {% endfor %}
        </ul>
      </li>
      {% else %}
      <li>
        <a href="{{ child_link.url }}" {% if child_link.active %} class="current"{% endif %}>{{ child_link.title }}</a>
      </li>
      {% endif %}
      {% endfor %}
    </ul>
  </li>
  {% else %}
  <li>
    {{ link.title | link_to: link.url }}
  </li>
  {% endif %}
  {% endfor %}
</ul>

styles.scss.liquid

nav.main ul > li > ul > li.dropdown {
  position: relative;

  ul.dropdown {
    left: 175px; // if the gutters or any of the menu padding has been altered then this and the 'top' value below might have to be altered to match.
    top: -6px;
    position: absolute;
    opacity: 0;
    display: none;
    // the remainder is taken from line 302. Unfortunately we can't @extend nested styles.
    background: {{ settings.nav_dropdown_background_color }}; 
    list-style: none outside none;
    padding: 5px 15px; display: none;
    min-width: 180px;
    z-index: 99999;
    border: 1px solid {{ settings.border_color }};
  }
}

Can't get this to work either. Is it active still?
