from dropdown selection to multiline output

I'm trying to create pdf -form with Adobe XPro where I'll have several Ship-To addresses. What I would like to have is that the user could select the correct Ship-To party from the dropdown.

Since the pdf-form dropdowns are only single lines the dropdown selection could only show the name of the company (e.g. COMPANY A) and by selecting the wanted company, this would trigger the whole (multiline) address to pop-up as described below (on another text field is ok if needed)  

COMPANY A

Streetaddress 1

ZIP-1234 City A

Does anybody have an easy solution for this?
