listBox Component + external .txt

Bonjour,

Right now I’m using two dynamix text boxes on a stage that both call in external .txt files…

textBox A:

Calls in a .txt file that has a list of topics that, when click, executes an asfunction that changes textBox B.

textBox B:

recieves the asfunction from textBox A.

Here’s the question, can someone help me out with this by replacing the dynamic text boxes on the stage with a listBox component. The reason is because I want the user to be able to see the selection they have made and which topic they’re on.

Thank you in advance!
