Can I sort products variants in a Shopify collection using price when using a custom theme?

When you create a collection in Shopify, you can choose to sort the products by:

• Product title (A-Z),
• best-seller,
• price point,
• newest and lowest product, and
• preferred but manual sorting order.

However, the default sorting options may not be available if you're using a custom theme. Fortunately, there's a creative workaround to help you sort products by price, even when using a custom theme. You have to create a collection and then write a program code. Here, you may need to take help from a programmer. Or you can integrate a third-party app like Sortimize Collection Sort for your specific sorting requirements.
