Hi,
You need to edit the "address format" setting under the Checkout tab of the HikaShop configuration:
www.hikashop.com/support/documentation/5...ml#checkout_shipping
There, you need to change the tags so that they are displayed dynamically with a bit of PHP code.
Something like that:
<?php
$address = $this->params->get('address');
if($address->xxx == 'yyy') {
echo '{zzz}';
}
?>
where xxx is the column name of the field where the user can select between the choices, yyy is the "value" of the choice for which you want to display the other field, and zzz the column name of the other field you want to be displayed in such a case.
