[jQuery] Making a Sliding Tab Menu

[jQuery] Making a Sliding Tab Menu

Ok so im trying to make a sliding tab menu, The menu is already made
with animations and such, however now im trying to integrate the menu
with the Divs i have for each menu item. Would anyone know of any
tutorials that would help accomplish this? I really just need
something to start me off..
Basically on click i want the current selected item and div to fadeOut
to the left and the newly selected to fadein from the right... any
help would be appreciated thanks

    }
    else
