Liquid For Tag

Using For Tag

Liquid for tag iterates Shopify collections with limit and offset.

Introduction to Liquid For Tag

The Liquid for tag is a powerful construct in Shopify's Liquid templating language, enabling developers to iterate over collections, such as arrays or lists of products. This tag is particularly useful for displaying a list of items, paginating large sets, or applying transformations to each item in a collection. In this guide, we will explore how to effectively use the for tag with limit and offset attributes to control iteration.

Basic Syntax of the For Tag

The basic syntax for the Liquid for tag is as follows:

Here, collection is the array or collection you want to iterate over, and item represents each element within that collection during the iteration.

Using Limit and Offset

The limit and offset options allow you to control the number of iterations and where to start iterating in the collection, respectively. The limit attribute specifies how many items to display, whereas offset defines the starting point in the collection. This is particularly useful for pagination.

In this example, the loop will iterate over the products array within the collections.frontpage object, starting from the 11th product (due to the offset of 10) and displaying a total of 5 products.

Reversing the Order of Items

You can also reverse the order of items in the collection using the reverse attribute. This attribute can be combined with limit and offset to further control the output.

In this code snippet, the products are iterated in reverse order, starting from the 11th product and displaying 5 items in total.

Conclusion

The Liquid for tag is an essential tool for iterating over collections in Shopify themes. By utilizing the limit, offset, and reverse attributes, developers can build sophisticated navigation, pagination, and product displays. Mastering these options opens up many possibilities for enhancing the user experience on Shopify sites.
