I'm not following. Do you want the form to open with all the values already in the drop down, or do you want the values to populate the dropdown after clicking on the dropdown? Or are they supposed to change based on something else?
Use an inline command that calls an ipl file. There is an example of how to do this in hereiwhome\examples\Templating\config\example_server_side_inline_callout.ipland hereiwhome\examples\Templating\templatedata\internet\yacht\datacapture.cfgIf you want to get the data from some other source other than a txt file you can make your own calls in your custom ipl file.
How about using [PHP][/PHP] inside the select?
