Shopify » Multi-line text

A Shopify Multi-line text works similar to the ACF type Text (with its "Lines" setting set to more than 1 line). There is no functional difference, but the Liquid code has a new syntax. Being a Shopify data type, that returns a Metafield object, the value property returns the actual value:

<h3>{{ product.metafields.accentuate.subtitle.value }}</h3>

A Shopify Multi-line text cannot store more than 65,535 characters (this includes any HTML tags)

Storing HTML in a Multi line text field

Since the Shopify field types don't yet offer a 'html' option, we have made it possible to treat the Multi line text field as HTML:liquid

With this setting enabled, you get the same editing functionality from ACF as for our native HTML field type.
