I want to specify a selection value in the source so that the list appears to be selected.
However, select a value to the list selection does not change the display.
Buttons are also a good idea.
The program has no right answer
However, my program is difficult to implement with a button because the number of variables in the list varies from 1 to 200.
I looked for an extension, but I haven’t found it yet.
Thank you.
