Third-party libraries: React Select MIT

                        
        
            Survey.StylesManager.applyTheme("modern");

    get options() {
      return this.question.visibleChoices.map((c) => {
         return {value: c.value, label: c.value }
      });
    }
    // Retrieve an option object based on the question value
    get selectedOption() {
      return this.options.filter((o) => o.value == this.question.value);
    }
    // Set the question value to the selected option value
    onSelectChange = (selectedOption) => {
      this.setValueCore(selectedOption.value);
