Instructions

This script is based on (this)[https://github.com/programmerhabib/load-more-button-on-shopify-collection-page/blob/main/load%20more%20product%20button.txt]

I’m using the Dawn Theme with Tailwind. To get this visually work you will need to install tailwind. Otherwise you have to write your own CSS for the Button + Spinner.

1. Add Next page as data attribute to product grid on your collection page: data-next-url="{{paginate.next.url}}" Looks like this in Dawn:

<ul id="product-grid" data-id="{{ section.id }}" class="flex-grid product-grid ..." data-next-url="{{paginate.next.url}}">

2. Add main-collection-product-grid.liquid content to the end of the grid on your collection page.
3. Include the script on the collection page

   {% if template contains 'collection' %}
     <script src="{{ 'collection-load-more.js' | asset_url }}" defer="defer"></script>
   {%endif%}

4. Check the class name of your product items / card (default is .grid__item if different change Line 26 in the javascript file.

Hi,
if it helps, I solved the problem like this:

 for (let i = 0; i < new_products.length; i++) {
    let single_product = new_products[i].cloneNode(true);
    products_on_page.appendChild(single_product);
}

It works for me.
