Overcome 100 limit of variants using Metafields - Impulse Theme

Technical Q&A

Topic summary

A developer is building a phone case store with 90+ device models and 2 case types (Snap and Tough), creating approximately 200 variants—exceeding Shopify’s 100-variant limit per product.

Proposed Solution:

  • Use metafields to display options as fake variants
  • Redirect users to separate products based on selection
  • Saw a YouTube demo of this technique for a different theme

Current Status:

  • Using Impulse theme
  • Wants to learn implementation independently
  • Provided example product URLs for yellow zebra snap and tough cases

Expert Response:
The responder confirmed this is possible as an advanced theme customization but noted the question is too broad for forum discussion. Implementation requires:

  • Custom variant option UI building
  • Metafield structure setup
  • JavaScript for link generation and redirects
  • Approach varies significantly by theme and store structure

Suggested starting with Shopify’s official variant documentation. For actual implementation, recommended contacting directly for custom development services with full store context (theme name, URLs, post URLs).

I need some help with Metafields. I am developing a Phone Case store. I have already 90 models of devices options. And we also have 2 types of phone cases. Snap or tough. Since Shopify allows only 100 variants per product, creating 2 types of cases for 90+ models of phones, that’s around 200 variants. I saw a demo for overcoming the limit by using metafields, display the metafields as variants and once the variant is selected, it would redirect to another product. But it was for a different theme and just to offer a custom quote. I want to learn this by myself. I am using Impulse theme.
Let me know if it’s possible.

If your a dev start here: https://shopify.dev/docs/themes/product-merchandising/variants

Beyond that you need to drastically narrow the scope of the question.

Yes of course it’s possible as an advanced theme customization.

It’s beyond the scope of a forum conversation, what your asking is overlay broad per implementation and also vague because of how many individual parts there are while not providing any work on code so far.

Your asking how metafields work, and how to not just fake variants in a select but build a custom variant option selection UI, and how to build links in javascript, and how to redirect, etc etc etc ad nausem.

All of which varies WILDLY by theme and store structure.

If you need this customization actually built for you then contact me by my email for services.
