The Theme Side Cart integration allows your quiz to use your store’s built-in cart drawer instead of redirecting customers to the default cart page.
Supported themes
Below is a list of themes with built-in side carts that we currently integrate with:
Dawn
Impact
Focal
Split
Concept
Enterprise
Sahara
Shine
Eurus
Expanse
Baseline
Please note: If you’re using a custom cart drawer or a theme that’s not listed above, unfortunately, your cart drawer will need a direct integration with Lantern, and it won’t work correctly otherwise. Please contact our support team for more details.
How cart drawers work with quizzes
Cart drawers (also called AJAX carts or side carts) only work inside your store.
This means they will only open correctly when the quiz is:
Embedded in your store as a section on a page using the app block key
Opened in a pop up using the pop-up URL
If the quiz is opened as a standalone link or being previewed, it is no longer inside your store, so the cart drawer cannot open directly.
Before you start
Make sure:
Your theme supports a built-in side cart
Lantern Core is enabled in your theme
Enable Lantern Core
Lantern Core must be enabled for cart functionality to work correctly.
To enable it:
Go to Online Store → Themes in Shopify
Click Customize on your live theme
Open App embeds
Turn on Lantern Core
Save your changes
This allows Lantern to communicate with your store’s cart and trigger the cart drawer.
Enable Theme Side Cart in your quiz
Open your quiz
Go to the Results Page
Open Reviews, Cart, Subscriptions
Select your theme from the Cart & Side Cart Drawer dropdown
Republish your quiz
Recommended settings
Use the following settings:
Do not open cart page: OFF
Open cart page in new tab: ON
These settings ensure the best experience in all cases:
If the quiz is inside your store (as a pop up, embedded or on a dedicated in-store page), the cart drawer opens automatically
If the quiz is in Preview mode or opened as a standalone link, a new tab opens in your store and triggers the cart drawer there
This fallback is needed because cart drawers cannot open outside your store.
Common issue
If nothing happens after clicking “Add to cart”, check that:
“Do not open cart page” is turned off
The quiz is being opened outside your store without a fallback
If you have any issues or need help setting this up, please contact our support team using the in app chat toggle or our e-mail at [email protected].
