How to Activate the App on a Theme

Before Rubik Variant Images & Swatch can control your product gallery or display swatches, you need to activate the app on your Shopify theme using the App Embed system.

This guide explains how to enable both the variant image gallery and the swatch picker.





  1. Open the Rubik Variant Images & Swatch app.
  2. Go to the Activated Themes tab.
  3. Select your live or draft theme from the dropdown menu.
  4. Click Enable on Theme Editor. Shopify will open the theme customizer automatically.
  5. In the theme editor, open the App Embeds panel on the left side.
  6. Toggle Rubik Variant Images & Swatch to ON.
  7. Click Save to apply your changes.


Once enabled, Rubik Variant Images & Swatch will start controlling variant image behavior on your product pages.



2. Enable Swatches on Your Theme


  1. In the Rubik app, click Swatch (Variant Picker) from the left menu.
  2. Toggle Swatch Status to Enabled.
  3. Select your theme and click Enable on Theme Editor.
  4. Shopify will open the theme customizer.
  5. Go to App Embeds and toggle Rubik Swatch to ON.
  6. Click Save.


After activation, swatches will replace Shopify's default variant dropdowns.



You can enable both the gallery and swatch features on multiple themes. This is ideal if you want to test your setup on a draft theme before publishing it live.
