Weird behaviour in cascading select

Hi @sumankhanal, Welcome to the community! Seems like you have some coding error within your xlsform. I tried at my end with the information you provided and i got it correct. For details, please see the images below: In the survey tab of your xlsform: [Image 1] In the choices tab of your xlsform: Please note, you may not see all the choices in the image as i have hidden it to save space. But you should find all the choices in the reference xlsform shared at the end of this post. [Image 2] …

But looking at your xlsform, i see there are more then 800 choices which should affect your data entry performance. Thus a solution for this could be designing a form combining cascading select question type with select_one_from_file question type as outlined in the image below:

Data entry screen as seen in Enketo:

Reference xlsform:
select_one_from_file.xlsx (15.8 KB)

Reference csv file:

Please feel free to have a look at our support article Select one or many from external file question type to learn more on select_one_from_file question type.

Have a great day!
