This one is a little more full featured as far as sharing is concerned. I may just give this one out so I added my site graphics so it looks a bit more professional. Demonstrates using a parent ‘folder’ for (sub) context menu items. Its pretty basic: create a handle (var hp) and a parent (which is nothing more than a context menu item with just a title) and use it in each child’s creation function inside the “parentId” property. I would have liked to put the proper site icons next to each menu item, but it does not work like that in Chrome. You can, however, use check boxes and radio buttons in the menu items. Maybe that will be included in the next version of Chrome (hopefully).

If you plan to use a library when creating your extension, be sure to use one that doesn’t use dynamic loading (unbuild dojo apps will not run in other words). In my opinion you should use straight javascript targeted at Chrome. This extension assumes its user is smart enough not to share a page that’s on the hard drive without hosting it on the Internet first (otherwise you’ll be sharing a file path). I could have used a Match Pattern in the “documentUrlPatterns” property in the creation function for each menu item that could check the scheme, but I didn’t bother. Its something you could use at your own discretion in your add-on.
