Filter by Product Options
From Kalles 1.3, we have updated a new Filter feature by Product data. With this feature, you don't need to enter tag like the old method, everything will show as automatically.
This method can only use for a store have less than 1000 products. If your store has more than 1000 products, it will be working incorrectly.
We strongly recommend only show 20 products per page on the collection page so the filter will work with the best performance. Please follow this guide for a config https://kalles-docs.the4.co/theme-settings/collection-page/collection-page#1-general-settings
