Show provinces of a region and hide the other provinces

Nord Gourcy
Nord Titao
Bassins Tuy
Bassins Houet
Bassins Kene
Sud Gaoua
if we have regions of a country. each region has provinces. for example:

we send investigators to each region. So that there is no error, I want that if an investigator chooses his region in the telephone, he only sees the provinces of the region that he must investigated.
how to do this condition?

Hi @pasme2,

Welcome to the community! You could do the same by using the cascading select function in KoBoToolbox.

For details on how to use the cascading select, please see the support article here.

Additionally, you could also have a look at some of the discussions that has happened related with cascading select in the community here.
