I would like to add a drop-down menu, what it is for doesn't really matter, but what does matter is:
1) I'd like it to display upon checkout and/or in the shopping cart.
2) I'd like for the selection to be sent to the admin via e-mail and/or within the invoice itself.
3) In the users processed orders or payments area I'd like it to display what they selected as text (like an online invoice)
How easily is this done?
