Are Custom Fields and Fees automatically added to the PDF ticket invoice?

Hello.

I have multiple custom fields for merchandise and with fee field activated. 

Will all my custom fields with fees be automatically added to the [REGISTRATION_DETAIL] and invoice under "Ordered Items"? Or is this something I need to configure/add in the PDF / Invoice setting?

Thank you! 

What kind of registration you are using? Individual/Group Registration Or Shopping Cart ?

I'm using Event Booking with individual/group registration. For my event, I have t-shirts and about seven products they can pre-order with their ticket. For these eight add-on merchandise, I'm creating new custom fields if they want to buy in addition to their individual / group ticket.

On a group registration, these fee options are selected for each group member? Or it is selected for whole group only ?

Just for information, the options are not supported at the moment. But I am trying to see if we have a way to support it in the future

Regards,

Tuan

I am using Ticket Types which does have these custom fields and their fee field as checkboxes.
