If statement on Invoice

Is there a way to hide an item on the voices if the item was not selected on the registration form? My problem is that we have two different events, but one has come custom field questions. The custom fields are show up on both events invoices even though they are not listed on both. 

Nevermind, Just removed the label text I manually added and just using the shortcode.

OK. If you have similar request in the future, consider look at Conditional Text feature eventbookingdoc.joomservices.com/basic-setup/conditional-text
