As you can read in the documentation of slideToggle, you’ve got a callback. You can use a callback to have an effect in and effect.
So let’s say you want to slideToggle the main div and want the div within that div to be shown with the jQuery function show().

On that way you can add a animation (or so) on a “moving” object. Is this what you meant?
