I have a form with a drop down field with the name of 30 attorneys that we contact.

Once the attorney is chosen from the drop down field I would like the other fields to automatically get populated. These include

[Attorney Address]
[Attorney City][Attorney State][Attorney Zip]
[Attorney Tel]
[Attorney Fax]

However if the attorney is not in the drop down field then the other fields can be entered manually.

A second question related to the first is the following: Can a drop down field be entered manually if the choice is not in the drop down menu.

For example. Suppose there are 5 attorneys in the drop down field but the document will have a new attorney's name, is there a way for a field to do double duty, both as a drop down and as a manual entry. This would help immensely.
