I'm looking for a sliding effect like this: http://www.piccante.co/sliding-doors/index.htm
But it's for MooTools and I need a jquery version which has a very nice and smooth motion.
Could you suggest such a plugin?
AFAIK these are called horizontal accordions. This is a pretty good library for jQuery:
Demos - the designs are not that pretty, but in the examples in the lower sections you can see that you can put any content you want on the handles too.
Or take a look at a more polished looking one
And finally to make it three: simple & nice, ready for your custom styling
I know that 3 is the magic number, but I stumbled across another one, that is pretty nice too.
Have fun!
