Is it possible to make the ElementId a required attribute for the Select2 Widget?  We have teams that were using this widget and left the ElementId blank which causes a Javascript error:

Uncaught ReferenceError: $select is not defined

This appears to be due to this Javascript code being produced:

<script type="text/javascript">
    $(document).ready(function () {
        $select.select2({containerCssClass: ':all:', allowClear: false, minimumResultsForSearch: 0, tags: false, closeOnSelect: true});
        if ($select.hasClass('ThemeGrid_MarginGutter')) {
            var $select2Element = $select.filter('.ThemeGrid_MarginGutter').next('.select2-container');
            if ($select2Element) $select2Element.addClass('ThemeGrid_MarginGutter');
    }});
</script>

The Javascript error is fixed by providing an ElementId in the Select2 widget attributes.  It would be better to have this required such that ServiceStudio could prevent publishing with the error.  Thanks!
