Shopify Online Store 2.0 allows you to add third-party app widgets (such as review stars, product badges, and wishlists) directly as modular blocks inside your theme sections, without modifying theme code.
️How to Add App Blocks
- Open the Theme Editor.
- Navigate to the page and section where you want to add the app widget (e.g. the product details column under Product Main Info).
- In the sidebar, click Add Block.
- Scroll to the bottom of the block list to find the Apps category.
- Select your target app block widget (e.g., your reviews widget).
- Drag and drop the block to adjust its vertical order.
- Click Save.
