Link `isRelated` schema.org to parent `Product` when not contained in child element

Question

I\'m trying to indicate multiple related products on a product page using schema.org microdata. But the child products are orphaned because they are not contained in the par

Answer 1

You don’t use itemref correctly.

You’d have to specify itemref on the main product instead of the related products:

<div itemref="product-1 product-2" itemscope itemtype="http://schema.org/Product">
  <span itemprop="name">Product</span>
</div>

<div id="product-1" itemprop="isRelatedTo" itemscope itemtype="http://schema.org/Product">
  <span itemprop="name">Product 1</span>
</div>

<div id="product-2" itemprop="isRelatedTo" itemscope itemtype="http://schema.org/Product">
  <span itemprop="name">Product 2</span>
</div>
