Cart drawer configuration with a custom theme | Delivery Gateway Help Center

By default, the Delivery Gateway app on Shopify supports the following themes:

If you wish to use a custom theme for your Shopify store, you need to manually specify CSS selectors for your cart drawer configuration.

For example, the configuration could look like this:

{
  "drawerSelector": "#CartDrawer",
  "drawerContainerTarget": ".cart-drawer-price-total",
  "containerInsertPosition": "below"
}

drawerSelector is the CSS selector for the main cart drawer element.
drawerContainerTarget is where you want to place the Delivery Gateway widget.
containerInsertPosition defines whether you want to insert the widget above or below the container target.

Note that you might need to modify the code of your theme to make your configuration work.
