MenuItem.type

By Opera Software

From Opera 15 onward, Opera 11 & 12’s extension format is no longer supported, and instead, we’ve switched to Chromium’s extension model. Check out our new documentation for developing extensions for Opera 15 and higher and start building your own extensions.

Description:

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.

Syntax:

DOMString type

Example:

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"/>
    ...
</widget>

//
// 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
  menu.addItem(item);
  // Add the sub-menu items to the main menu item
  item.addItem(itemEnglish);
  item.addItem(itemJapanese);
}
