Hi, I am developing a large custom apparel store at [login to view URL] I am switching from WooCommerce to Magneto because of scalability issues. We are still in the development stage. I am looking to copy the functionality of the product options chooser located here: [login to view URL] Here are the basic requirements of the options chooser: A. List 25 pieces of apparel icons. 10 main apparel icons, with 15 sub apparel icons from a slide-out. B. The customer selects an apparel icon, and then a set of available colors appear for this individual apparel piece, and also a set of available sizes. Each apparel may come in different sizes and colors. Yet, inventory is not required. We are print on demand, so everything is in stock. C. Upon click apparel/color, the URL, dynamic SKU, title, description, picture all update. To give you even more detail.. Here is also an existing plugin that does much but not all of the above... [login to view URL] All easy so far... Now for the hard part... I don't have enough letters in this box... Please see attached "magento [login to view URL]" for full detail.
