Muliple languages in multi-select dropdown question

I have a multi-select drop down question. Everything works as it should, but our QC people realized that the text showing up in the drop down is in English only.
Working Code

<script>
$(document).ready(function(){
	// Settings
	var searchable = false;
	var closeDropdownOnSelection = true;
	var hideInputElements = false;
	
	var closedDropdownSymbol = '▼';
	var openedDropdownSymbol = '▲';
	var placeholderDropdownText = 'Type to search';
	var noResultsDropdownText = 'No results found';
	var closedDropdownText = function(selectedItems) {
		// Good preset for checkboxes: shows "X options selected" if an item is selected, or "Select options."
		var numberOfSelectedItems = selectedItems.length;
		switch (numberOfSelectedItems) {
			case 0:
				return 'Select Route(s)';
				break;
			case 1:
				return '1 option selected';
				break;
			default:
				return numberOfSelectedItems + ' options selected';
				break;
		}
	}

				return '<div class="language" data-language="1">
						Select Route(s)
						</div>
						<div class="language" data-language="2">
						Something other than English
						</div>';
				break;
