chrome.contextMenus

Description

Use the chrome.contextMenus API to add items to Google Chrome's context menu. You can choose what types of objects your context menu additions apply to, such as images, hyperlinks, and pages.

Permissions

contextMenus

You must declare the "contextMenus" permission in your extension's manifest to use the API. Also, you should specify a 16 by 16-pixel icon for display next to your menu item. For example:

{
  "name": "My extension",
  ...
  "permissions": [
    "contextMenus"
  ],
  "icons": {
    "16": "icon-bitty.png",
    "48": "icon-small.png",
    "128": "icon-large.png"
  },
  ...
}

Concepts and usage

Context menu items can appear in any document (or frame within a document), even those with file:// or chrome:// URLs. To control which documents your items can appear in, specify the documentUrlPatterns field when you call the create() or update() methods.

You can create as many context menu items as you need, but if more than one from your extension is visible at once, Google Chrome automatically collapses them into a single parent menu.

Examples

To try this API, install the contextMenus API example from the chrome-extension-samples repository.

Types

ContextType

Chrome 44+

The different contexts a menu can appear in. Specifying 'all' is equivalent to the combination of all other contexts except for 'launcher'. The 'launcher' context is only supported by apps and is used to add menu items to the context menu that appears when clicking the app icon in the launcher/taskbar/dock/etc. Different platforms might put limitations on what is actually supported in a launcher context menu.

    [ContextType,...ContextType[]] optional

    List of contexts this menu item will appear in. Defaults to ['page'].

    string[] optional

    Restricts the item to apply only to documents or frames whose URL matches one of the given patterns. For details on pattern formats, see Match Patterns.

  • parentId

    string|number optional

    The ID of a parent menu item; this makes the item a child of a previously added item.

  • targetUrlPatterns

    string[] optional

    Similar to documentUrlPatterns, filters based on the src attribute of img, audio, and video tags and the href attribute of a tags.

  • title

    string optional

    The text to display in the item; this is required unless type is separator. When the context is selection, use %s within the string to show the selected text.

    The onclick function looks like:

    (info: OnClickData,tab: Tab)=> {...}

    • Information about the item clicked and the context where the click happened.

    • tab

      The details of the tab where the click took place. This parameter is not present for platform apps.
