How to allow selecting color and multiple quantity options on product page.

[IonForge]

Hello.

I am quite new to Shopify and one of my prospects who want to order multiple quantity with various color options that we do provide (4 color options). However, when he try to check out, he can only choose one color with multiple quantities and cannot add two quantities with two different colours. He also try to add one with one colour and add another with different colour but it replace older one so cannot add both.

I guess that I need to change settings but not sure how. Can anyone help me out on this please?

Here is the product page customer wants to add into cart with multiple quantity with different color options.

Hi @IonForge 

I guess you removed Add to cart button from buy-buttons.liquid file of your theme, which is why you cannot add optional to cart.

Thank you so much. May I ask how to add Add to Cart button back please?

It has an option to revert that file to the previous version/

Hi @IonForge 

Welcome to Shopify!

The issue you're describing usually happens when the product has color options (like variants), but the customer is trying to add multiple variants (e.g., 1 Red + 1 Black) in a single action, which Shopify's default behavior doesn't support directly. Each variant needs to be added to the cart separately.

Now, if you’re looking for a smoother quantity-based selling experience — especially when you want to offer tiered pricing or bulk discounts (like Buy 3, Save 10%) — I’d recommend checking out the Wizio Bundle – Quantity Breaks app.

With Wizio, you can:

• Offer quantity discounts
• Create variant-specific quantity bundles
• Customize discount labels
• Show savings directly on the product page

While Wizio doesn’t change how variants are selected in the cart, it enhances the quantity selection and pricing logic, which can improve the shopping experience — especially for B2B or bulk buyers.

Let me know if you'd like help setting it up or have any questions. 😊

Thank you. I am actually looking for free solution instead of paid app to add on if possible. 🙂

Understood,

Here because you have setup variants as color, it will pick that variant only with multiple quantities.
Some sort of customization development might required on that product page in order to achieve that feature without an app.

Let us know if you want us to help with that, our shopify storefront development team can do that for you.
