PHP контактная форма электронной почты

Я создал контактную форму электронной почты PHP, и она работает. Теперь, кроме того, я использовал Javascript для добавления дополнительных раскрывающихся списков в форму, в которой пользователь может выбрать вариант. Я бы хотел, чтобы эти выбранные параметры из новых выпадающих списков были добавлены в текст сообщения электронной почты для электронной почты PHP.

Просто интересно, может ли кто-нибудь помочь.
