Un object passé au méthodes menus.create() ou  menus.update()  pour décrire les propriétés de l'élément de menu nouveau ou mis à jour.

checked Facultatif
boolean. The initial state of a checkbox or radio item: true for selected and false for unselected. Only one radio item can be selected at a time in a given group of radio items.
command Facultatif

string. String describing an action that should be taken when the user clicks the item. Possible values are:

  • "_execute_browser_action": simulate a click on the extension's browser action, opening its popup if it has one
  • "_execute_page_action": simulate a click on the extension's page action, opening its popup if it has one
  • "_execute_sidebar_action": open the extension's sidebar

Clicking the item will still trigger the menus.onClicked event, but there's no guarantee of the ordering here: the command may be executed before onClicked fires.

contexts Facultatif

array of menus.ContextType. Array of contexts in which this menu item will appear. If this option is omitted:

  • if the item's parent has contexts set, then this item will inherit its parent's contexts
  • otherwise, the item is given a context array of ["page"].
documentUrlPatterns Facultatif
array of string. Lets you restrict the item to apply only to documents whose URL matches one of the given match patterns. This applies to frames as well.
enabled Facultatif
boolean. Whether this menu item is enabled or disabled. Defaults to true.
icons Facultatif

object. One or more custom icons to display next to the item. Custom icons can only be set for items appearing in submenus. This property is an object with one property for each supplied icon: the property's name should include the icon's size in pixels, and path is relative to the icon from the extension's root directory. The browser tries to choose a 16x16 pixel icon for a normal display or a 32x32 pixel icon for a high-density display. To avoid any scaling, you can specify icons like this:

"icons": {
      "16": "path/to/geo-16.png",
      "32": "path/to/geo-32.png"

Alternatively, you can specify a single SVG icon, and it will be scaled appropriately:

"icons": {
      "16": "path/to/geo.svg"

Note: The top-level menu item uses the icons specified in the manifest rather than what is specified with this key.

id Facultatif
string. The unique ID to assign to this item. Mandatory for event pages. Cannot be the same as another ID for this extension.
onclick Facultatif
function. A function that will be called when the menu item is clicked. Event pages cannot use this: instead, they should register a listener for menus.onClicked.
parentId Facultatif
integer or string. The ID of a parent menu item; this makes the item a child of a previously added item. Note: If you have created more than one menu item, then the items will be placed in a submenu. The submenu's parent will be labeled with the name of the extension.
targetUrlPatterns Facultatif
array of string. Similar to documentUrlPatterns, but lets you filter based on the href of anchor tags and the src attribute of img/audio/video tags. This parameter supports any URL scheme, even those that are usually not allowed in a match pattern.
title Facultatif

string. The text to be displayed in the item. Mandatory unless type is "separator".

You can use "%s" in the string. If you do this in a menu item, and some text is selected in the page when the menu is shown, then the selected text will be interpolated into the title. For example, if title is "Translate '%s' to Pig Latin" and the user selects the word "cool", then activates the menu, then the menu item's title will be: "Translate 'cool' to Pig Latin".

If the title contains an ampersand "&" then the next character will be used as an access key for the item, and the ampersand will not be displayed. Exceptions to this are:

  • If the next character is also an ampersand: then a single ampersand will be displayed and no access key will be set. In effect, "&&" is used to display a single ampersand.
  • If the next characters are the interpolation directive "%s": then the ampersand will not be displayed and no access key will be set.
  • If the ampersand is the last character in the title: then the ampersand will not be displayed and no access key will be set.

Only the first ampersand will be used to set an access key: subsequent ampersands will not be displayed but will not set keys. So "&A and &B" will be shown as "A and B" and set "A" as the access key.

type Facultatif
menus.ItemType. The type of menu item: "normal", "checkbox", "radio", "separator". Defaults to "normal".
viewTypes Facultatif
extension.ViewType. List of view types where the menu item will be shown. Defaults to any view, including those without a viewType.
visible Facultatif
boolean. Whether the item is shown in the menu. Defaults to true.
