What I mean is the following, that when the user writes in the first name field, a piece of data appears in the last name field.
For example, in the LayoutProcessor.php I can define the values that they are going to have, but it needs a trigger, and I would like to know if it is possible to autocomplete the surname field, when the name field has a value.
$jsLayout[‘components’][‘checkout’][‘children’][‘steps’][‘children’][‘shipping-step’][‘children’][‘shippingAddress’][‘children’][‘shipping-address-fieldset’][‘children’][‘firstname’][‘value’] = ‘Yone’;
$jsLayout[‘components’][‘checkout’][‘children’][‘steps’][‘children’][‘shipping-step’][‘children’][‘shippingAddress’][‘children’][‘shipping-address-fieldset’][‘children’][‘lastname’][‘value’] = ‘Dawnbringer’;
