Unexpected UI for manual run of an embedded server that only allows CSV downloads

[mullen2]

Note: the following was originally posted by @aarenson here: IUREDCap/redcap-etl#38, and I am moving it here, since it applies to the REDCap-ETL external module.

After configuring the embedded server to be CSV only and then going to a project and testing out a manual run of a configuration, I found it momentarily confusing that there was a dropdown list to choose 'Export data as CSV zip file'.

In contrast, for another defined server there is no dropdown list at all.

I expect that the reason for this discrepancy is that for remote servers there never can be more than one choice, while for the embedded server there could be a choice.

I wonder if a less confusing interface might be to always have the drop down list, whether using the embedded server or another server, and always have the two possible choices (remote execution and CSV file), but to gray out the available choice if only one choice is available.

Alternatively, if there is only once choice, perhaps replace the dropdown with text noting what will happen (remote execution, CSV file).
