# Movie clips and components

The components available in the Components panel (Window > Components) are simply movie clips that have been programmed with certain properties and behaviors. Like any movie clip, some of these components are visual (the Accordian or ListBox components, for example) and others are non-visual (the WebServiceCall component, for example). Advanced programmers can create their own components for their own use, or package the components for easy distribution. For more information about using and creating components, see Using Components.
