Hi!

Now, how can I create "menu in menu" in Slahdot Menu, I don't want that "Image Optimizer" to be linkable but to be menu like "Online Tools", like this:

+ Online tools //this is menu
+ + Image optimizer //I want this to be menu too
+ + + Some text //Now this should be linkable
+ + Favicon Generator //This should be menu too
etc.

Something like this:
