Problem with standard addressing

Hello,

I also have a problem with the addressing in my form.

Im making a simple fax-form for a company to send as first page of a fax.

In the form I need to address it to someone as followed
to: mister ....
to: miss ....

In Dutch:
t.a.v. de heer ....
t.a.v. mevrouw ....

The .... has to be typed by the user of the form.

A bit later you have to start the fax form as followed:
Dear mister ....,
Dear miss ....,

In Dutch:
Geachte heer ....,
Geachte mevrouw ....,

The problem is that you can only address in those two ways, so no miss, mam, hey Mike!, Dear Jane Doe, etc.

If I try to use a drop-down box after to/t.a.v. or after Dear/Geachte the problem is that the words aren't of the same length, so the name of the person (textfield) has a too big, or a too small, or a correct white space before it.

This is really ugly, but I don't know another way to solve this problem.
Do you have any ideas?

Thanks a lot in advance!

Sterre
