Hi,

You can develop a Joomla plugin of the group "hikashop" and implement the fields API in it in order to add your own type of custom field :

An example of such plugin is the "advanced date picker" custom field type plugin that you can find in plugins/hikashop/datepicker_field/ with the Business edition.
