multi-line textbox into a dropdown

[Elan28074581a7un]

Is there a way to export a multi-line textbox into a dropdown? 

Chat GPT gave me this, but it did not work

var multilineTextField = this.getField("MultilineTextField"); // Replace with the actual name of your multiline text field
var dropdownField = this.getField("YourDropdownFieldName"); // Replace with the actual name of your dropdown field

var optionsText = multilineTextField.value;
var options = optionsText.split("\n");

dropdownField.clearItems();

for (var i = 0; i < options.length; i++) {
    dropdownField.addItem(options[i]);
}

addItem doesn't exist in Acrobat.

Use this:

var multilineTextField = this.getField("MultilineTextField").valueAsString.split(/[\r\n]+/);
this.getField("YourDropdownFieldName").clearItems();
this.getField("YourDropdownFieldName").setItems(multilineTextField);
