Edit a selected dropdown value

Hi, 

I am trying to get the values of a dropdown in a textbox and user should be able to update that value. I am building an app where I need to generate a pdf which outlines the conditions for a particular student. Every student has different condition based on the subject that they have taken. I want to outline a general condition in the dropdown and user should be able to update the subject for a particular student. I am trying to get selected dropdown value in a textbox and update that. I am able to get the value of the dropdown with app formula but textbox is not editable. Is there any other way to make it work? 

Thank You!
