Create a Choice list From Existed submission

[Kal_Lam]

I want to have a select_one question whose values are updated with every submission, and these values are the name of the beneficiaries. that because i want to make this question autocomplete so that when i write just a few letters, this question will be filtered and then i can pick up the name from the filtered choices

So, do you mean you wish to have the text question entered previously shown as a choice? Did you also mean this should be on the same form, or can the text question be updated in Form A and the text that was entered on Form A be a choice for select_one question type in Form B or should it be a choice in Form A?
