# Integrate with Theme

Cart Drawer is an embed app on Shopify and will work separately from the main function of Shopify. For this reason, merchants would have to activate the App inside the Theme to acquire this design.

## Activate Opus Cart Drawer Cart Upsell

### Activate inside the app

This method will ensure the app is activated on your live theme

Once logging into our app, the first page you see will be the Dashboard page. There will be 2 sections to activate our app on this page. The first thing is that you can toggle on the text line on the top of the page. It will direct you to the Activation page. Then hit Save to Activate our app on your published theme. You can also click on Integrate with Theme button on the Step 3. This will also direct you to the Activation page and you can repeat the same function with the first method.

### Activate on Online Store

You can activate app on any themes that you want, both active and draft one.

First, navigating to the Online Store section, click on Themes.
