Hello,
We're using ODK to collect data relative to hospitals in various countries.
The first questions are typically about selecting a province/district and
then the facility using a cascading select.
The problem is that for our biggest project we have more than 20 000
facilities at the last level. We managed to create the form and upload it
using the ONA service, but it won't open in ODK (it wait for a long time
then crash).
Our current solution has been to "split" that form into identical parts
dedicated to each province, but it's not really practical.
Any advice/experience with very large choices? The ODK doc refer to the
option of putting long lists into separated CSV file, has anyone
experience with this?
Thanks a lot,
Martin

Hi Martin,
Are you using the pull csv function or are you creating the entire list in
the form? If it's in the form it's likely it will crash due to its size.
Give pull csv a shot. I think it would work for you.
Thanks,
Matt

Hi Matt,
Thanks for the quick reply - for now we are putting the choices directly in
the form. I saw the doc about the CSV option, but I was interested in
experience/validation on that choice (it's a bit of work on our side) -
which you just provided, so I'll try it.
Regards,
Martin

Yes definitely give it a shot. It's designed specifically to help address
this use case. Enketo has also been updated to help handle very large CSV
lookups too without compromising on performance.
