Partial tag is being recognized as an unknown tag in the Shopify code editor

Theme Store

Description:

I’m encountering an issue in the Shopify code editor where the partial Liquid tag is highlighted as an unknown tag, even though it is valid according to the Shopify Liquid documentation.

For example:
{% partial ‘liquid-tip’ %}

The editor immediately shows the following error:

FileSaveError: Liquid syntax error (line XX): Unknown tag ‘partial’

This appears to be happening at the editor/parser level rather than during syntax highlighting alone, as it also prevents the file from being saved.

I’m trying to understand:

  • Is the partial tag currently supported only in specific Shopify environments (for example, Shopify Theme Store themes, developer preview, or feature preview)?
  • Does it require enabling a feature or using a specific Liquid version?
  • Has anyone else experienced the same issue, and if so, what was the resolution?

I’ve attached a screenshot showing the error.

Any clarification would be appreciated.

Hi,

This is expected for now - the {% partial %} tag is currently only available under developer preview. According to Shopify’s docs, you need to enable “Liquid July '26 changes” from the available feature previews.

Here’s the reference: Partial tag
