Hello,
We are looking for a possibility to use a select_one (or select_multiple) type as hidden for an internal calculation. This will allow to define and export labels, e.g. for Excel or SPSS, for this variable.
We tried things like appearance=hidden or deactivated column = yes, without solution. The latter seems to fully exclude the question, even in export (except in form download) and works in Enketo, but gives a warning in https://getodk.org/xlsform/
