Ensure you’ve turned on “OneTick Upsell Cross Sell” in your theme editor > App embeds for optimal functionality.

After creating your checkbox, the ‘Install Checkboxes‘ modal will appear. You can access this feature by clicking on the “View installation guide” at the top right corner of the page.
In the modal, look for the ‘Go to Theme Editor‘ button and click it to open the editor.
If you want to leave the checkbox for later use, you can also find the ‘View installation guide‘ again in the checkbox editor page. Simply look for the ‘View installation guide‘ button at the top right of the checkbox editor page, and click on it to open the widget.
You can also go to the theme editor a different way: Go to your Shopify admin, then choose ‘Online Store‘, then ‘Themes‘. Select your current theme and click ‘Customize‘.
Step 3: Add OneTick Checkbox App Block To Your Section![Copy Click to copy](https://help.ecomate.co/wp-content/themes/manual/images/icons/link.svg)
In the theme editor where you want the checkbox, click ‘Add block‘ in the section. Then, under ‘App blocks‘, choose ‘OneTick Upsell Cross Sell‘.
Remember, you can only use OneTick checkbox in sections with product details, like ‘Featured Product‘ (on pages other than product pages) or ‘Product Information‘ (on product pages).
Now, your checkboxes are ready! Click the ‘Save‘ button to make the changes appear on your website. All checkboxes that have an “Active” status and have been selected for that trigger product will be displayed on your store. You can change the order of the checkboxes in the OneTick app.
