Hi 
On product’s page in options and variations’ tab in dashboard, when you click on the checkbox:
Options have different prices, SKUs or stock levels
nothing happend.
impossible to set a price addition depending the options recorded.
perhaps i miss a detail on config ?
Against each option there is a selector: ‘In Variations’
That needs to be set for the options that should create different variations of the product.
Once you set those, you should start to see the variation combinations listed underneath the variations section (and checkbox you mentioned)
ok just understand it’s just for option list, it’s not available for checkbox, thanks for your help
