How to create pick_list item by text file?

Hi, I use iced-rs 0.13.1 and i use example from iced/examples/pick_list at 0.13.1 · iced-rs/iced · GitHub

I want to read data from text file and make it into pick_list.

How did I do ?

Please, specify what are you trying to accomplish - do you want to read from file once or each time certain event happens? What kind of difficulty are you experiencing in your implementation attempts?
