Project contained 4 products. All products had different properties. End user can change properties and price of product would change according to selected properties.

So for that I needed to create draft order with custom product and price and list all required properties in checkout in Shopify.

Wherever products appear and with them swatches appear, I needed to change whole product when clicking on swatch occur without redirection.

Also built custom quick view for product.

Needed some custom functionality in product template. When user changes option variants, he would see other only enabled option variants in dropdowns.

Product Image Zoom, Mobile menu and other navigation menu changes.
