Chrome extension: add option to right click menu when clicking certain HTML element

Question

I want to create a Chrome extension that adds an option to the right click menu when the user right clicks a certain HTML element (for example a DIV with a known ID).

I would use this to add an option when the user right clicks a tweet on Twitter.com and that option would call a REST service.

Is this posible with a regultar Chrome extension?

Yes, these are called Context Menus. You can find the docs for those here: https://developer.chrome.com/extensions/contextMenus
