This documentation relates to Opera's now deprecated .oex Extension API framework for Opera versions <= 12.15 and also provided by our OEX2NEX shim library.

The type attribute is used to define the type of a menu item. The list of valid type values includes entry, folder and line. This attribute defaults to a value of entry.


DOMString type


The following example creates an item with type folderin the context menu. This is not clickable — instead, sub-menu items will appear when hovered over or otherwise activated. These sub-menu items have the default type which is entry, and so they are clickable.

  The configuration file ('config.xml').
<?xml version='1.0' encoding='utf-8'?>
<widget xmlns="http://www.w3.org/ns/widgets">
    <feature name="opera:contextmenus"/>
// The background process (e.g. index.html)

if (opera.contexts.menu) {
  var menu = opera.contexts.menu;
  // Create menu item properties objects
  var itemProps = {
    title: 'Translate this page',
    type: 'folder'
  var itemPropsEnglish = {
    title: 'English',
    onclick: function(event) {
      doTranslate(event.pageURL, 'English');
  var itemPropsJapanese = {
    title: 'Japanese',
    onclick: function(event) {
      doTranslate(event.pageURL, 'Japanese');

  // Create menu items with the specified properties
  var item = menu.createItem(itemProps);
  var itemEnglish = menu.createItem(itemPropsEnglish);
  var itemJapanese = menu.createItem(itemPropsJapanese);
  // Add the menu item to the context menu
  // Add the sub-menu items to the main menu item
