The Bundle products section allows you to display a curated set of products and sell them together as a single bundle, making it easy for customers to purchase a complete set. Please follow this document to learn how to configure this section.

Below are some general settings you should pay attention to
Color: You will change the color in the color scheme. Follow this document to understand more.
Images: You can upload separate images for desktop and mobile devices.
Desktop Position: Choose whether the image is displayed on the left or right side on desktop.
Enable Quick View: Enable or disable the Quick View feature for bundle products.
Show Vendor: Enable this option to display the product vendor name.
Show Total Price: Enable this option to display the total bundle price (including discounts) below the product list.
Use Hotspots: Enable or disable hotspots on the image. This option is available from version 2.1.0 and later.

You can add up to 6 products in this section, meaning a maximum of 6 products can be included in a single bundle. When customers click “Add to Cart,” all products in the bundle will be added to the cart at the same time
In case you want to show a discount when purchasing bundle products together, you can use one of the following methods:
Set a Compare at price directly for each product.
