About the code to write to the drop-down list field.

I have set the items in the dropdown list as follows.

var l = this.getField("Dropdown1");
l.setItems(["One", "Two", "Three"]);

This will certainly show "One", "Two", "Three" in the drop down list.
However, when actually using it, for some reason only "One" can be selected.

Even if I select "Two", "One" is displayed.

I created a button for trial and wrote the code there.
In this case, it worked as planned.

Why can't I just write the code directly in the drop-down list?
Is it possible to achieve the goal without creating a new button?

This kind of code only needs to execute once, or when the options change. When you use setItems it resets the field to the default value (the first item in the list), which is probably what is happening in your case.
