Creates a new context menu item.
You must pass an options object defining properties for the item. You may also pass a callback that will be called when the item has been created, or if an error occurred during creation.
If the browser encounters an error it will set runtime.lastError
, and you can check for this in the callback.
Syntax
chrome.contextMenus.create( createProperties, // object function() {...} // optional function )
This API is also available as browser.contextMenus.create()
in a version that returns a promise.

Examples
This example creates a context menu item that's shown when the user has selected some text in the page. It just logs the selected text to the console:
chrome.contextMenus.create({ id: "log-selection", title: "Log '%s' to the console", contexts: ["selection"] }); chrome.contextMenus.onClicked.addListener(function(info, tab) { if (info.menuItemId == "log-selection") { console.log(info.selectionText); } });
This example adds two radio items, which you can use to choose whether to apply a green or a blue border to the page. Note that this example will need the activeTab permission.
function onCreated() { if (chrome.runtime.lastError) { console.log("error creating item:" + chrome.runtime.lastError); } else { console.log("item created successfully"); } } chrome.contextMenus.create({ id: "radio-green", type: "radio", title: "Make it green", contexts: ["all"], checked: false }, onCreated); chrome.contextMenus.create({ id: "radio-blue", type: "radio", title: "Make it blue", contexts: ["all"], checked: false }, onCreated); var makeItBlue = 'document.body.style.border = "5px solid blue"'; var makeItGreen = 'document.body.style.border = "5px solid green"'; chrome.contextMenus.onClicked.addListener(function(info, tab) { if (info.menuItemId == "radio-blue") { chrome.tabs.executeScript(tab.id, { code: makeItBlue }); } else if (info.menuItemId == "radio-green") { chrome.tabs.executeScript(tab.id, { code: makeItGreen }); } });
