Magento

I want to add a product with add-on options, and we should be able to manage the inventory of main product as well as add-ons. Also, its not compulsory to select add ons. We want to add product Similar to this product. I have tried to implement it in two ways: 1. Using configurable products: Added a configurable product and added associated products. [Problem: Associated products becomes compulsory to select and also we are not able to manage inventory of the main product. 2. Using Bundled Products: Added a Bundled product and then assigned associated products to it. But here also we can’t manage the inventory of the main bundled product. Please help.

The page you linked too is using a “simple product” and adding custom options to that product.

(but like you said you won’t be able to manage the inventory of the add-on options)
