Thx a lot everyone, I work it out with all your help!!!

Dear PaulThx a lot!I got them on the ddlist in preview function in LiveCycle Designer, but when I open the pdf with Adobe Reader, nothing in ddlist, I placed the .xml file in same directory with the pdf file already, I also tried attach the .xml to the pdf by acrobat but still the same.  Do you know...

Dear allI have a dept.xml as below.<?xml version="1.0" encoding="UTF-8"?><departments> <department>Account</department> <departmentAdmin</department> <department>Safety</department></departments>May I know what is simpliest way to fill "Account", "Admin" and "Safety" into a drop down list?  And how?...
