Custom Curtains / shades website

[raunhar]

I want a website like http://www.customfurnish.com/curtains-online/?name=FLAT%20PANEL%20CURTAIN#curtainFabrics

Using Custom Fields I could do a page like http://raunharman.com/curtains/custom-eyelet-curtain.html ( I am using Joomla 3.5 with Virtuemart 3.0.14)

However, you will notice that I have offered to choose Fabric by Text dropdown menu, whereas I want to choose by fabric swatch image, as shown in the customfurnish.com website

I use this product:
https://breakdesigns.net/extensions/customfields-for-all

I am not sure how to get it to show patterns, but it is excellent for colours!

You can display many options as image,name,short desc, sku. and with some little php knowledge echo any product informations.
