Setting up jQuery for Widgets
Custom Fields Widgets require jQuery to function to display properly. Adding jQuery to your Shopify theme is very easy!
Step 1: Copy the following snippet for jQuery 3.5.1
<script src="https://code.jquery.com/jquery-3.5.1.min.js" integrity="sha256-9/aliU8dGd2tb6OSsuzixeV4y/faTqgFtohetphbbj0=" crossorigin="anonymous"></script>
If you need a different version of jQuery you can find more snippets at code.jquery.com.
Step 2: Visit your Themes settings page in your Shopify store and select "Actions > Edit code".
Step 3: Open your "theme.liquid" file and search for "widgets.js".
Step 4: Paste the jQuery snippet before the "custom-fields-widgets.js" code.
Step 5: Save, and check your widgets to see that they are working now!
