[Shopify-only] How to display kiwi size chart in featured product section on home page?

This would require updating the theme code by adding the kiwi snippet. 

First, open the theme code editor, and open the file featured-product.liquid

Next in the liquid file, find where you want the size chart to display, and then insert the following code:

<!-- START KiwiSizing code !-->
<div id="KiwiSizingChart"
  data-collections="{{ product.collections | map: 'id' | join: ','}}"
  data-tags="{{ product.tags | join: ',' | escape}}"
  data-product="{{product.id}}"
  data-vendor="{{product.vendor | escape}}"
  data-product-name="{{product.title}}"
  data-product-images="{{product.images | json| escape}}"
  data-type="{{product.type | escape}}">
</div>
<!-- END KiwiSizing code !-->
