how do i add a login menu to superfish menu module? I thought i would be able to add the default User Login menu to a Superfish block, but it doesn't appear in the drop down list to be able to select when configuring the Superfish block. 

Can anyone advise how to create a login menu for superfish that disappears when users are logged in. I have my Main Menu in Superfish 1 block, and my User Menu (contains logout) in my Superfish 2 block (works perfectly as only appears when logged in), and wanted a Superfish 3  for User Login (to only appear when logged out).

Perhaps there is an easier way to do this, so open to suggestions?
Instead of using SuperFish, you should consider using:
