List<OptionElement> selectedOptions

## Implementation

    List<OptionElement> get selectedOptions {
      // IE does not change the selected flag for single-selection items.
      if (this.multiple!) {
        var options = this.options.where((o) => o.selected).toList();
        return new UnmodifiableListView(options);
      } else {
        return [this.options[this.selectedIndex!]];
      }
    }
