Topic summary

A user seeks to add a custom badge on product cards in the Yuva theme to display available sizes, similar to the existing sale badge.

Proposed Solutions:

  • Variant Swatch King app: Recommended for displaying size/variant information on product cards

  • Product Labels & Badges app by BSS Commerce: Suggested for creating custom inventory badges using variables like {inventory} or {inventory_quantity}. The feature is available on the free plan through: Add new badge > Custom Badge Text > Choose variable > Select products

Hi @chacha420

We checked your needs and would like to suggest you use Product Labels & Badges app. This app lets you create a custom badge to show the inventory badge.

Please go to the app > Click on Add new badge > Choose Custom Text Badge > Choose a variable named {inventory} or {inventory_quantity} > Choose the applied products.

These will help you show available sizes for your products. Also, this feature is available for all users, including those on our free plan.

We hope it will help you!

Hi @chacha420 ,

Please refer the below video how you can implement multiple badges on product card page. Code is independent to theme therefore it will work for your theme too.

Hope this will helps.
