Hi @Ivan_Pavkovic, it is possible to pre-load the names of the users and use the search appearance to search for any name which in part of the pre-loaded data by starting to type the name you are looking for, it will be sorting the names base on the letters you begin typing with.
I've saved a cvs file in my media /odk/forms/formname-media folder on your phone and included _key at the end of the column name where I would like my survey to read/reference the cvs file (in the media folder). However it does not appear with any options.
My understanding is that if I want to pull data (from a defined list of data) I would use the pulldata function. However I want my survey to only provide the option of utilising data from the cvs file in the media folder. I don't want to retain the option for them to just enter the data in by themselves.
