if (opera.contexts.menu) {
  var menu = opera.contexts.menu;
  // Create a menu item properties object
  var itemProps = {
    title: 'Translate page into English',
    onclick: function(event) {
  if (window.navigator.browserLanguage.indexOf('en') != 0) {
    itemProps.disabled = true;

  // Create a menu item with the specified properties
  var item = menu.createItem(itemProps);
  // Add the menu item to the context menu
