create a fragment with web service to populate the drop down list

Hello,

Can any one please advise/suggest on how to create a fragment in LiveCycle Designer ES with web service to populate the drop down list so I can re-use it for another form. I already have a drop down list to populate the data from the web serivice but need some advise on how to create a fragment for this drop down list so I can start to embed it in other forms as well.

Thanks in advance,

HD
