Add the App Block to Your Theme

Gallery Wall requires a dedicated theme template and an app block so the builder displays on your product pages.

Step 1 – Create a New Theme Template

  1. In your Shopify admin, go to Online Store > Themes.
  2. Click Customize on your active theme.
  3. In the theme editor, click on the Templates dropdown and select Products.
  4. Click Create template, name it Gallery Wall, and click Create.

Step 2 – Configure the Template

  1. In the new Gallery Wall template, find Product Information in the left panel and hide it (click the eye icon to toggle off).
  2. Click Add section and search for Gallery Wall Editor (the app block). Add it.
  3. Position the Gallery Wall Editor section where Product Information was. Use drag-and-drop to reorder.
  4. Click Save.
The Gallery Wall Editor app block replaces the standard product information section. Customers will see the gallery builder instead of the default product layout.
