So i am using my product designer for Shirts designing. As seen as attached are the colours that can be chosen for the T shirt.

But my shirts will have different materials and different materials will have different colours, can it be done that there is an option such as drop down where people choose the material firts, eg:dryfit or cotton and once material chosen only the colours that will be available for that material will be listed.

Thanks

Theres no way of using drop down lists for variations to change the product designer but the developer has another plugin that will work like your wanting it to with thumbnails of the materials you have for your tshirts. http://fancyproductdesigner.com/product/sneaker-mspc/

Theres also another way you could do it & use this method: http://fancyproductdesigner.com/product/hats/
You could implement your different materials that way like the Hats demo & change the label from "Change Products" to Change "Material".

Hope some of these ideas may of been some use to you.
