Hi, I'm using Drupal commerce for an event registration website. When we sell event tickets as product we would require Attendee names and details for each ticket. we used line item field to store attendees details. However, we would need an extra feature, which is: when a customer add more than one product/event to his/her cart, then there must be more than one atteendee's name field to fill in. For example if the customer choose 3 tickets in the shopping cart quantity field, then there must be two fields to fill in for attendee's names... Does anyone know how to do this? I tried, rules, but no luck with that!
