Product metafields not showing as a dynamic source

Store Design

Topic summary

A user is unable to display product metafields as dynamic sources in collapsible tabs on product pages, specifically for YouTube video URLs.

Setup attempted:

  • Created a metafield with content type “URL”
  • Added YouTube URLs to individual products
  • Metafields display correctly when editing products but don’t appear as dynamic source options in the theme customizer
  • Using Showcase theme

Key findings:

  • Only “single line text” and “multi-line text” metafield types appear as dynamic sources for collapsible tabs
  • URL and other content types are not showing as available options
  • Dynamic source availability is context-dependent according to Shopify documentation

Proposed solutions:

  • Change the URL metafield to a simple text metafield instead of URL type
  • Alternatively, use custom Liquid code to embed the link inside an IFRAME (requires coding)
  • May need to modify the stock template or hire an expert if coding assistance is needed

The issue remains unresolved, with the user seeking a simple solution without additional backend coding.

Hi everyone -

I’m trying to put a YouTube video link on the product pages under a collapsible tab. The steps that I followed are:

  • Create a Metafield with content type URL

  • Add for each product the respective YouTube URL (if there is one)

  • When I go to Customize the Product Page, I select collapsible tab, and when I click on insert dynamic source the Metafield that I created doesn’t appear

I’m using Showcase. Any advice on why the Metafields are not showing? I’ve done a ton of trial and error, and while the Metafields are showing as expected across the products when editing, they do not appear as an option when attempting to insert them as a dynamic source for a Product Page.

Thanks in advance!

Hi @kdigitalstudio
In this case I think to check and fix the problem, we need to check your code and theme customize to clear how you added the function.
Can you share the store information, then we can help you check and fix it.

Here’s a preview of the theme since the store is not active: https://rep3q7pputd9x6ep-56186404931.shopifypreview.com

When and how dynamic sources are available is determined by context , outlined in this doc

Hi @kdigitalstudio
If you want to display a video on product with dynamic source using metafield.
You need to write liquid code embed the link inside IFRAME.
If you not comfortable with the code, you need to hire an expert, who can help you do that,
Or if you can share your store access, I will spend time to help you check it.

It’s not crucial for me to have the thumbnail of the video under the collapsible section. I tried using an HREF link with multi-line text, and cannot find a simple way to link YouTube videos dynamically. Is this not possible with metafields and collapsible tabs without additional coding in backend?

Based on that reference the dynamic source should appear for the collapsible tabs. Currently, only the content type “single line text” and “multi line text” (aside from product title, description, price) are available as dynamic sources for a stock template I’ve downloaded. Attempting to try any other content type (page reference as a popular example for size charts) does not work either.

Unless you want to get mired in implementation details just make the url metafield a simple text metafield instead.

Otherwise that stock template has to be modified and experimented with to see if there’s a 100% solution.
