Hi,
I want create a bundle with total 3 products.
Product 1 and 2 are Mandatory and Product 3 you can choose out of 5 other shopify products. You can only choose one of them.
Best practice would be Classic Bundle incl SKU in shopify and choose 2 products mandatory and product 3 flexible. I test several apps but still not what i’m looking for or to complex
Check BundleJoy: you can create a kit with 3 items:
in Item #1 and Item #2 you can set your mandatory products and in Item #3 you can include the other 5 products from which only one can be selected.
Here you can find a demo (store pass: joy)

Hi @Roydonck79
I recommend using Easify Product Options to create this bundle. It allows you to set mandatory products and give customers the option to choose from a list of products for the third item. This way, you can easily set up the bundle with the flexibility you need. Here’s how it works:
- If you want the mandatory products to be chosen automatically, you can set both the minimum and maximum quantity to 2, and enable both products to 'Default’
The app is very easy to use!If you need any further assistance or have any questions, feel free to reach out 
Hello @Roydonck79
To create a bundle with mandatory and flexible product options in Shopify, specifically where Product 1 and Product 2 are mandatory, and Product 3 is optional but must be selected from a set of 5 options, here’s a solution using the iCart Cart Drawer Cart Upsell app:
Steps:1. Install iCart Cart Drawer Cart Upsell:
- From your Shopify admin, go to the Shopify App Store.
- Search for iCart Cart Drawer Cart Upsell and install it.
-
Create the Bundle Using iCart:
- Open the iCart app and go to the Product Bundles section.
- Create a Custom Bundle with the following setup:
- Product 1 and Product 2 should be mandatory (fixed, added automatically).
- Product 3 will be the flexible option, where customers can choose one from 5 options.
-
Use Variants or Custom Options for Product 3:
- If Product 3 is one of 5 items, you can set it up as a variant of a “bundle product” or use custom options within iCart.
- Add a selection widget in the iCart app that lets customers pick from the 5 available choices.
-
Set Conditions for Mandatory Products:
- Use the app’s functionality to ensure that Product 1 and Product 2 are automatically added to the cart.
- For Product 3, make sure customers can only select one product from the 5 available options.
Hi @Roydonck79 ,
This is very much possible with our app Profit Bundles. I understand your requirement we called these bundles as custom bundles where customers pick what goes inside the bundles.
I am also sharing the guide on how to set it up in the app.
thank you. And you see as a separate product in the collection like normal product?

It won’t appear as a separate product but you can add a banner on the product page that will redirect the user to the bundle page.
