To display all the color variants of a single product on your collection page, without creating individual products for each color.

These instructions apply to Dawn theme version 5.0.0.

In the Dawn theme code, open the main-collection-product-grid.liquid file, it’s in the Sections folder.

Look for the <ul> list tag that displays the product grid.

Update the code between the <ul> ... </ul> tags to this:

            <ul id="product-grid" data-id="{{ section.id }}" class="
              grid product-grid grid--{{ section.settings.columns_mobile }}-col-tablet-down
              grid--{{ section.settings.columns_desktop }}-col-desktop">
              {%- for product in collection.products -%}
             
                {% assign lazy_load = false %}
                {%- if forloop.index > 2 -%}
                  {%- assign lazy_load = true -%}
                {%- endif -%}

        
             {% for option in product.options %}
         	    {% if product.options_by_name['Color'].values == null %}        
                   <li class="grid__item">     
                   {% render 'card-product',      
                    card_product: product,
                    product_title: product.title,
                    media_aspect_ratio: section.settings.image_ratio,
                    show_secondary_image: section.settings.show_secondary_image,

                  %}
                  </li>
               {% endif %}
  			 {% if option == 'Color' %}

 		     {% assign colorlist = '' %}
  			 {% assign color = '' %}
  			 {% for variant in product.variants %}
  			 {% capture color %}
 		     {{ variant.options[index] }}
             {% endcapture %}
             {% unless colorlist contains color %}            
                <li class="grid__item">
                  {% render 'card-product-variant',
                    card_product: variant,
                    title: product.title,

                  %}
                </li>
     	 {% capture tempList %}
      	 {{colorlist | append: color | append: " " }}
     	 {% endcapture %}
     	 {% assign colorlist = tempList %}
      	{% endunless %}
      	{% endfor %}          
      {% endif %}
    {% endfor %}
    {%- endfor -%}
    </ul>

To correctly display the variant, create another version of the card-product snippet file.

In the Snippets folder create a new file called card-product-variant and add this code:

{% comment %}
    Renders a product variant card

    Accepts:
    - card_product: {Object} Variant Liquid object (optional)
    - media_aspect_ratio: {String} Size of the product image card. Values are "square" and "portrait". Default is "square" (optional)
    - show_secondary_image: {Boolean} Show the secondary image on hover. Default: false (optional)
    - show_vendor: {Boolean} Show the product vendor. Default: false
    - show_rating: {Boolean} Show the product rating. Default: false
    - extend_height: {Boolean} Card height extends to available container space. Default: true (optional)
    - lazy_load: {Boolean} Image should be lazy loaded. Default: true (optional)
    - show_quick_add: {Boolean} Show the quick add button.
    - section_id: {String} The ID of the section that contains this card.
    - color: the variant color.
    - title: product.title

    Usage:
    {% render 'card-product-variant', show_vendor: section.settings.show_vendor %}
{% endcomment %}
