product-metafield-keys.md

Creates an array of metafield keys for a given namespace (replace "namespace" below with actual metafield namespace).

{% assign product_metafields = product.metafields["namespace"] %}

{% assign product_metafield_keys = "" | split: "" %}

{% assign keys = product_metafields | json | split: "," %}

{% for k in keys %}
  {% assign key = k | split: ":" | first | remove: '"' | remove: '{' | remove: '}' %}
  {% assign key = key | split: "-<-@" %}
  {% assign product_metafield_keys = product_metafield_keys | concat: key %}
{% endfor %}

Once we have the keys, we can loop through them dynamically.
