Create drop down field for contact populating with dynamic data

Can a drop down field on a IS web form be populated from a file(csv, text, etc) that has been uploaded to the files area that contains the possible values to select from?

The data in this file(+/- 3000 entries) can be uploaded nightly if any changes to the values need to be updated or new entries added.

We are trying make sure an invalid value(not in our database) is not entered into a field.

TIA,
Billy

Any uploaded file can only be downloaded…not read. To do what you’re asking, it would be necessary to be able to read the file every time a webform is loaded by someone and that’s not possible. You could host a file somewhere else, but then the webform would have the key html elements stripped out of it anyway.
