Navigation System

Horizon’s navigation system features rich mega menus with support for images, featured products, featured collections, and multi-level navigation. On desktop (≥750px), the header displays a horizontal mega menu:

<header-menu class="header-menu" data-hydration-key="header-menu">
  <nav class="menu-list" aria-label="{{ 'accessibility.header_navigation_label' | t }}">
    {% render 'overflow-list',
      class: 'overflow-menu',
      children: children,
      minimum-items: 2
    %}
  </nav>
</header-menu>

Mobile Drawer

On mobile (below 750px), navigation switches to a drawer menu:

{% case variant %}
  {% when 'mobile' %}
    <div class="header__drawer" ref="headerDrawerContainer">
      {% render 'header-drawer',
        linklist: block_settings.menu,
        data_header_drawer_type: 'mobile-drawer'
      %}
    </div>
{% endcase %}

Optional horizontal scrolling navigation bar for mobile:

{% when 'navigation_bar' %}
  {% if block_settings.navigation_bar == true %}
    <div class="menu-list menu-list--mobile color-{{ block_settings.color_scheme_navigation_bar }}">
      <div class="menu-list__scroll-container">
        <ul class="menu-list__list">
          {% for link in block_settings.menu.links %}
            <li>
              <a href="{{ link.url }}" class="menu-list__item">
                {{ link.title }}
              </a>
            </li>
          {% endfor %}
        </ul>
      </div>
    </div>
  {% endif %}
{% endcase %}

Features:

The mega menu supports four content types:

<a href="{{ link.url }}" class="mega-menu__link">
  {{ link.title }}
</a>

Grid System

Mega menus use a responsive grid:

<div class="mega-menu__grid" style="
  --menu-columns-tablet: {{ grid_columns_count_tablet }};
  --menu-columns-desktop: {{ grid_columns_count }};
  --menu-horizontal-gap: var(--gap-xl);
  --menu-vertical-gap: var(--gap-xl);
">
  {% render 'mega-menu-list',
    parent_link: link,
    grid_columns_count: 6,
    grid_columns_count_tablet: 4
  %}
</div>

Column Spans:

.mega-menu__column { grid-column: span 1; }
.mega-menu__column--span-2 { grid-column: span 2; }
.mega-menu__column--span-3 { grid-column: span 3; }
.mega-menu__column--span-4 { grid-column: span 4; }

Submenu Rendering

{% for link in block_settings.menu.links %}
  <li class="menu-list__list-item">
    <a href="{{ link.url }}" 
       class="menu-list__link"
       {% if link.links != blank %}
         aria-controls="submenu-{{ forloop.index }}"
         aria-haspopup="true"
         aria-expanded="false"
       {% endif %}>
      <span class="menu-list__link-title">{{ link.title }}</span>
    </a>
    
    {% if link.links != blank %}
      <div class="menu-list__submenu" ref="submenu[]">
        <div id="submenu-{{ forloop.index }}" class="menu-list__submenu-inner">
          <div class="mega-menu section section--full-width-margin">
            <div class="mega-menu__grid">
              {% render 'mega-menu-list', parent_link: link %}
            </div>
          </div>
        </div>
      </div>
    {% endif %}
  </li>
{% endfor %}
