How can I stop size variants from auto-selecting on product pages?

Store Design
, , ,

Topic summary

A merchant wants to prevent product size variants from being automatically pre-selected when customers land on product pages, preferring customers choose their own size manually.

Current Issue:

  • The first size variant auto-selects by default on product pages
  • Merchant is using Bullet theme with Globo product variants app

Responses & Findings:

  • One responder indicated this is Shopify’s default behavior and likely requires a third-party form app to change
  • Another suggested identifying the responsible code in the theme files
  • The merchant located problematic code using Chrome Developer tools: <input type="radio" checked="checked">
  • Removing the checked="checked" attribute solves the issue in browser, but the merchant cannot locate this code in the liquid theme files

Status: Unresolved - the merchant needs help finding where this auto-selection code exists in their theme files to permanently remove it.

Hello, when a customer lands on a product page, the first size variant is pre-selected. I do not want any sizes to be pre-selected. I just want the customer to land on the product page and choose their own size. If anyone can help, I would greatly appreciate it.

Hi @JhordanMSUITE ,
This is Richard from PageFly - Shopify Page Builder App.

This is not possible because this is the default from Shopify. Or you can use a 3rd app to do it (I think form-related apps will do it).

Best regards,

Hi @JhordanMSUITE , we have to identify the code responsible for the default variant to be selected, what theme are you using?

Hi @Abdosamer , I found this in the Chrome Developer

when I remove it, the problem is solved. I can’t find the code in the liquid file. I am using Bullet theme, but using the Globo app for product variants. So, if I can find the above code in the liquid file and remove it, all will be solved. Maybe you can help?
