Hi,
In order to click through the variants, each consecutive variant has to be a child click selector of the previous one. See example below:
{"_id":"etsy-variants","startUrl":["https://www.etsy.com/listing/1729022605/personalized-toddler-geometric-and"],"selectors":[{"clickActionType":"real","clickElementSelector":"#variation-selector-0 option:not(:contains('Select a color'))","clickElementUniquenessType":"uniqueCSSSelector","clickType":"clickOnce","delay":0,"discardInitialElements":"discard-when-click-element-exists","id":"click01","multiple":true,"parentSelectors":["_root"],"selector":"body","type":"SelectorElementClick"},{"clickActionType":"real","clickElementSelector":"#variation-selector-1 option:not(:contains('Select an'))","clickElementUniquenessType":"uniqueCSSSelector","clickType":"clickOnce","delay":0,"discardInitialElements":"discard-when-click-element-exists","id":"click02","multiple":true,"parentSelectors":["click01"],"selector":"_parent_","type":"SelectorElementClick"},{"id":"color","multiple":false,"parentSelectors":["click02"],"regex":"","selector":"#variation-selector-0 option[selected]","type":"SelectorText"},{"id":"letters","multiple":false,"parentSelectors":["click02"],"regex":"","selector":"#variation-selector-1 option[selected]","type":"SelectorText"}]}
