Hi Rio,

I implemented something similar, where I had a list of 5000+ individuals
and we needed to select one from the list.

Here is how you can do it:

  1. Make a CSV file with name of bird species in one column and return code
    an another cloumn.
  2. Create a text input field in your form before the select one prompt.
  3. Create select one prompt with search function in appearance column.
  4. Sample code to put in appearance is : search('hhdata', 'startswith',
    'full_name', ${A1_Name})
    Here,
    hhdata = name of the csv file without extension.
    startswith = search the names which start with ...
    full_name = column name in csv file
    ${A1_Name} = variable to get the search text from the text filed we created
    in step 2.

Now, when you load this form, the select one prompt will show only the
names which start with text in input field which will generate much smaller
select one list. For example: if you enter K in the text input field, then
the select one filed will show only names that start with K.

Hi Micth Susdt,

I just see and try your suggestion, but I think that is the cascading with external choices, and the problem the cascading is is not works good on repeat group.

do you have any idea for make search engine for select one.?

By search engine, I think you mean some sort of autocomplete widget?
It's non-trivial, code contributions are always welcome!
