First of all, you really cannot add additional menu items to the standard context menus. But you can disable the context menu using a specific CSS property. So the solution would be to disable the default menu and implement your own from scratch. And to implement your own context menu, you first need to catch the tab and hold gesture, get the coordinates of the finger on the screen, translate these coordinates into the coordinate system of the web page, and finally look for HTML elements in this place.

you can fire the event as follows:

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
  if( navigationType == UIWebViewNavigationTypeLinkClicked )
  {
    // Handle your URL click here (open the popup menu)
    // ...
    return NO;
  }
  return YES;
}

don't forget to delegate UIWebView
