Shopify always uses the latest version of Liquid as a base, but Shopify adds a significant number of objects, tags, and filters to Liquid for use in merchants' stores. These include objects representing store, product, and customer information, and filters for displaying store data and manipulating storefront assets like product images.
|
||||
|
||||
Shopify's version of Liquid is documented in the [Shopify developer documentation](https://shopify.dev/docs/themes/liquid/reference). If you want to try out Shopify's version of Liquid, you can create a development store through the [Shopify Partner Dashboard](https://help.shopify.com/en/partners/dashboard/managing-stores/development-stores).
|
||||
Shopify has several versions of Liquid. The most popular version is used to build Shopify themes. To learn about the Liquid elements that you can use to build Shopify themes, and to learn about the other versions of Liquid at Shopify, refer to the [Shopify Liquid reference](https://shopify.dev/api/liquid).

Creates a switch statement to execute a particular block of code when a variable has a specified value. `case` initializes the switch statement, and `when` statements define the various conditions.
|

|

A `when` tag can accept multiple values. When multiple values are provided, the expression is returned when the variable matches any of the values inside of the tag. Provide the values as a comma-separated list, or separate them using an `or` operator.

An optional `else` statement at the end of the case provides code to execute if none of the conditions are met.
