Change only the image inside same div when option from dropdown is chosen

阅读更多关于 Change only the image inside same div when option from dropdown is chosen

I have a nested form where you can add new bracelets to your order. For each bracelet you can choose a color, and next to the select (dropdown) where you choose the color there is an image with the bracelet on that color. The problem is this: When I add a new nested-fields div (form for new bracelet), when I select a color in the dropdown the image next to it doesn't change. Also, when I select a color in the dropdown for the first bracelet, the images for all the bracelets change to that color.
