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

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() method.

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.

Manifest

You must declare the "contextMenus" permission in your extension's manifest to use the API. Also, you should specify a 16x16-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"
},
...
}

Examples

You can find samples of this API on the sample page.

Summary

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.
