Conditions create rules that will show or hide an option based on the customer's previous selections. With conditions you can, for example, show an option only if another specific option is selected.
Since BigCommerce doesn't have native conditions, it is not possible to add them while creating the options set. However, you can add them later through the Customily Options App, as we show here.
