script.aculo.us Modules

The script.aculo.us is divided into modules, each with its own JavaScript file. These modules are explained here:

Effects: The effects module comes with more than twenty-five visual effects and seven transition modes.
Drag and drop: You will use the dragdrop module to make any element draggable, turn it into a drop zone, or even make entire series of elements sortable so you can rearrange them by dragging and dropping.
Sliders: A slider is a sort of small rail, or track, along which you can slide a handle. It translates into a numerical value. With script.aculo.us, you can create such sliders with a lot of control.
Autocompletion: Autocompleter controls allow for Google-Suggest style local and server-powered autocompleting text input fields.
In-place Editing: You can make any text or collection of items editable in-place by simply clicking it.
Builder: A helper to build DOM fragments in Java Script. This is a developer tool that eases DOM creation considerably.
Sound: Version 1.7.1 introduced a sound system that lets you play sounds easily, queue them up, use multiple tracks, and so on.
