MenuItem.title

This functionality has not landed in a stable Opera version yet, but you can use it already in Opera Next.

Description:

The title attribute represents the displayable name for a menu item. If the attribute is empty (default), the string in the <name> element of the extension's config.xml file is used.

Syntax:

DOMString title

Example:

The following example creates an item in the context menu with a specified title.

<!-- 
  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 a menu item properties object
  var itemProps = {
    title: 'Context Menu Example'
  }

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