How Integrate the SCLOGIN module in "Menu Superfish" ?

Egyptim,
Sorry for the delayed response. Are you looking to show the whole SClogin module, with the Joomla login/password fields or do you just want the Login With Facebook button?

There's a few different ways to do what you're looking for, but I need more information on what you want displayed, and how. If possible, can you post a URL to the site you're looking to implement this on so we can see the menu. Seeing that, along with your description of what you want, will help come up with a good solution.

Thanks,
Alex
