Setting up custom fields in Shopify Metafields – everything you need to know
In this article, I’ll show you how to add custom fields using Shopify Metafields, so you can make your Shopify shop even more appealing to your customers.
What are Shopify Metafields?
Shopify metafields are custom containers for products, variants, customers and other elements in your Shopify shop. Essentially, metafields allow you to expand on the standard information that Shopify provides for these elements.
The customisable data can be used in a variety of ways. Product customisation, the integration of third-party apps, improved filtering and search options, and the creation of bespoke layouts and displays on the website – all of this is made possible by Metafields.
What are the benefits of Shopify Metafields?
Shopify’s meta fields make it relatively easy to add information to your online shop that goes beyond the standard fields. This offers you the following benefits:
- More product information for customers.
- An improved user experience thanks to the filter function.
- Optimised SEO for Shopify.
What are the requirements for Shopify Metafields?
With Shopify OS 2.0, you can now set up Shopify Metafields natively within your Shopify CMS, so there’s no longer any need for complex setup procedures. You simply need to ensure that both your Shopify OS and your theme are up to date.
How do I set up Shopify Metafields?
To set up a new metafield, follow these steps:
You can find the settings for Shopify Metafields under the ‘Custom Data’ menu item.

Defining a metafield: You must specify the name of your metafield. A namespace is then generated automatically. This allows you to select the metafield later in the code. You cannot change this later.

Next, you can choose which type of Metafield you want to implement.

Filling in Metafields: You can now find the Metafield you have created in the relevant section of the backend. Product Metafields appear at the very bottom of the product pages. Here, you can now enter the information for the products of your choice.

And just like that, your additional information will appear in your Shopify shop.
How to display Metafields in your online shop
If you’re using an Online Store 2.0 theme, you can link almost all meta fields via the theme editor. This link can be set up in any position marked with the icon showing three discs.
With a single click, you can select the metafields you created earlier as the source.
How to edit Metafield definitions
If you always want to display meta fields in the backend as input options for products or categories, you can pin them using the pin icon.
To delete a Metafield definition, you should first ensure that it is no longer linked to a theme. Otherwise, display errors may occur. You can choose to delete either just the definition or the values as well.
You can edit the meta-field name, description and validation rules afterwards.
