Hi there !
We are building a website - which will allow users to add products to a product group which will then create a single product. An example of the functionality we are looking to achieve can be found here : https://www.zamplebox.com/subscribe#/categories
Users will choose the different flavours - which then create a single product and price.
I am trying to find a Magento Extension which will do this. I have sourced this extension : https://www.magentocommerce.com/magento-connect/best4mage-mix-match-custom-box-builder.html but I do not believe it will do what we are after.
Thanks in advance .
You can try the Advanced Product Options extension and provide your product groups as options. This ext has one significant advantage: you can control inventory of each custom options. That's how I see the solution for your issue.
You may also check the Dynamic Product Options extension for Magento. You can create group of options with images like on your example, and associate the options to other products if needed. Then you can divide the options into separate sections and make options dependent. For example, show Fruit flavors only if "Fruit" selected on the 1st step.
Hope it will be of help.
