Shopify Tags total items

Question

In Shopify, how do I show a list of tags followed by the number of products with that tag?

Example: Black(12), Blue(10).

Currently the code looks like this,

Answer 1

products_count is an attribute of collection, not tag.

I believe you would need to manually loop through the products and count the number with the specified tag.

For example:

{% assign collection = collections.all %}

<ul>
    {% for tag in collection.all_tags %}

        {% assign products_count = 0 %}
        {% for product in collection.products %}
            {% if product.tags contains tag %}
                {% assign products_count = products_count | plus: 1 %}
            {% endif %}
        {% endfor %}

        <li>
            <a href="https://mystore.myshopify.com/collections/all/{{ tag }}">
                {{ tag }}
            </a>
            ({{ products_count }})
        </li>
    {% endfor %}
</ul>

See these similar discussions on the Shopify forums:

Solution by Steph is working. But, if i have enabled grouped tags and want to show product count. Kindly let me know solution to append product count in following code:

'{%comment%} code for color, designer, material sidebar filter {%endcomment%}

          {%- for tag in collection.all_tags -%}
            
            {%- assign tag_parts = tag | split: '_' -%}

            {%- if tag_parts.size != 2 -%}
              {%- continue -%}
            {%- endif -%}

            {%- assign groups = groups | append: tag_parts.first | append: ',' -%} 
          {% endfor %}


    {%comment%} End of  code for color, designer, material sidebar filter {%endcomment%}'
