Do you mean populate the values of the drop with the data from the
datasource, or create a mailmerge document that contains a dropdown
formfield.
If it's the latter, the two features that you wish to use are mutually
exclusive. It could
however be done by using DOCVARIABLE fields instead of mailmerge fields and
using VBA to iterate through the datasource, creating a documnet for each
record and setting the value of the variables.

Hope this helps.
