A typical wiring for [if](https://docs.rual.nl/block-types/field%2520validation/fieldvalidation_branch): [required](https://docs.rual.nl/block-types/field%2520validation/fieldvalidation_required) feeds the `then` pin; [required](https://docs.rual.nl/block-types/field%2520validation/fieldvalidation_required) feeds the `else` pin; [==](https://docs.rual.nl/block-types/condition/condition_equal) feeds the `condition` pin; the `fieldvalidation` out pin feeds [radio](https://docs.rual.nl/block-types/Component%2520UI/component_radio).
