How variant mapping works

From options to steps

Each Shopify option (Color, Size, Carat…) can become a step. Choose how it looks — swatches, buttons, a size grid or a dropdown.

Sold-out combinations

Composa checks availability in order. If 18k White in size 9 is sold out, size 9 is disabled once 18k White is picked.

Mixed mode

Keep your variants for the main choices and add custom steps (engraving, add-ons) on top.
