Requirements of commenting out liquid code in Shopify

1. Using Comment Tags

This is the primary method for commenting out blocks of Liquid code.

Syntax:

{% comment %} (Start of the comment block)
The code you want to comment out goes here
{% endcomment %} (End of the comment block)

Example:

Code snippet

{% comment %}
  This is a multi-line comment.
  Any Liquid code or text within these tags will be ignored.
{% endcomment %}

2. Using Inline Comments with Liquid 5.4+

Introduced in Liquid version 5.4, this allows for single-line comments within Liquid code.

Syntax:


{% # This is an inline comment %}

Example:

Code snippet

{% if product.available %} 
<p>In stock</p> {% # Display "In stock" if the product is available %} 
{% endif %}

3. Using Raw Tags for Mixed Content

If you need to comment out Liquid code mixed with HTML or other content, use raw tags to prevent rendering.

Syntax:


The mixed content you want to comment out goes here

Example:

Code snippet


<h1>{{ product.title }}</h1> {% # This Liquid code won't be processed %}
