Metafiled doubt in theme development

Shopify Discussion

Topic summary

A theme developer is implementing customer review cards on a product detail page to display pros and cons, controlled via metafields. They have two main questions:

Key Questions:

  • Whether they’re responsible for adding metafields to the Shopify admin panel during development
  • If metafields will automatically appear for users who purchase the theme

Resolution:
Metafields are not automatically created when a theme is installed. The workflow is:

  1. User purchases and installs the theme
  2. User must manually create the required metafields
  3. User edits each product to enter metafield values
  4. Content displays only when metafield values exist

Recommended Implementation:
Use conditional statements to show content only when metafield values are present:

{% if product.metafields.namespace.key.value %}
  [content]
{% endif %}

Action Item:
Provide clear documentation to guide customers on creating and managing these metafields.

I’m developing a theme in which I have added two cards on my Product detail page for customer detail review in which one card will show the pros of customer reviews and one card will show the cons of customer detail review. But this will be work from the metafield. And I’m not very much aware about the metafiled I have just added the code so it will work from the metafiled.
So my question is during developing a theme it is my responsibility to add that pros and cons of metafiled in Shopify admin panel because I have added that code in my code. Or do i need to check that it is working fine or not.
And my second question is when user buy my theme so that particular metafiled will show them or not?

By default, metafields are not automatically created when the theme is installed. The user who purchases the theme must manually create these metafields and assign values to each product.

You can use a conditional statement to display the button only when the metafield value exists. For example:

{% if product.metafields.namespace.key.value %}
  
{% endif %}

Explanation:

  1. The user buys and installs the theme — metafields are not created automatically.

  2. The user must manually create the required metafields.

  3. The user then needs to edit each product and enter values for the metafields.

  4. Once the metafield has a value, the button will be displayed on the product page.

Make sure to provide clear instructions or documentation to guide your customers on how to create and manage these metafields.
