        section: section,
        children: children,

  {% assign products_per_page = section.settings.products_per_page %}
{% endif %}

{% paginate collection.products by products_per_page %}

    {% for product in collection.products %}
      <li id="{{ section.id }}-{{ product.id }}"
          class="product-grid__item product-grid__item--{{ forloop.index0 }}"
          data-page="{{ paginate.current_page }}"
          data-product-id="{{ product.id }}"
          ref="cards[]">
        
        {% content_for 'block',
          type: '_product-card',
          id: 'product-card',
          closest.product: product
        %}
      </li>
    {% endfor %}
  {% endcapture %}
  
  {% render 'product-grid',
    section: section,
    children: children,
    products: collection.products,
    paginate: paginate,
    enable_infinite_scroll: section.settings.enable_infinite_scroll
  %}
{% endpaginate %}

Product Card Attributes

ID

class="product-grid__item product-grid__item--{{ forloop.index0 }}"

Base class for styling
Index class for specific positioning

data-page="{{ paginate.current_page }}"

Infinite Scroll

Automatic product loading as users scroll:

Products Per Page

products_per_page:
  min: 8
  max: 36

  default: 24
  visible_if: enable_infinite_scroll == false

When infinite scroll is enabled, products per page is fixed at 24 for optimal performance.

Filtering System

Integrated filtering block for product discovery:

{% content_for 'block',
  type: 'filters',
  id: 'filters',
  results: collection,
  results_size: collection.products_count
%}

Filter Types:

Tags
Variants (color, size, etc.)
Price range
Availability
Vendor
Product type

Automatic scroll to products when using URL hash:

const url = new URL(window.location.href);
if (url.hash) {
  document.addEventListener('DOMContentLoaded', () => {
    const card = document.getElementById(url.hash.slice(1));
    if (card) {
      card.scrollIntoView({ behavior: 'instant' });
    }
  }, { once: true });
}

Usage:

/collections/all#product-123

Scrolls directly to product with ID 123.

View Transitions

Smooth animations when emptying cart:

html:active-view-transition-type(empty-cart-page) {
  .cart-items-component {
    view-transition-name: cart-page-content;
  }
}

::view-transition-old(cart-page-content) {
  animation: cart-page-content-old var(--animation-speed-fast) forwards;
}

Grid Column System

The collection wrapper uses a smart grid:

.collection-wrapper {
  display: grid;
  grid-template-columns: var(--grid-column--mobile);
}

@media screen and (min-width: 750px) {
  .collection-wrapper {
    grid-template-columns: var(--grid-column--desktop);
  }
}

With Filters:

--grid-column--mobile: 1fr;
--grid-column--desktop: 250px 1fr; /* Filters | Products */

Without Filters:

--grid-column--mobile: 1fr;
--grid-column--desktop: 1fr;

JavaScript Module

The collection list is powered by results-list.js:

<script src="{{ 'results-list.js' | asset_url }}" type="module" fetchpriority="low"></script>

Handles:

Infinite scroll detection
URL parameter management
Filter state
Page transitions
Analytics events

Performance Optimizations

Lazy Loading

{{ product.featured_image | image_tag: loading: 'lazy' }}

All product images are lazy-loaded by default.

Fetchpriority

<script src="{{ 'results-list.js' | asset_url }}" fetchpriority="low"></script>

Non-critical JavaScript loads with low priority.

Content Visibility

.product-card {
  content-visibility: auto;
  contain-intrinsic-size: 300px 400px;
}

Accessibility

ARIA Labels

<results-list role="region" aria-label="{{ 'accessibility.product_list' | t }}">
  <div role="list">
    <div role="listitem">...</div>
  </div>
</results-list>

Focus Management

When loading new products via infinite scroll, focus is managed to prevent disorientation.
