The Dreamweaver Components panel lets users load and work with components. It lists all the available component types that are compatible with each enabled server model.

Extensibility lets you add new component types to the panel. Follow several general steps when adding a new component type to the Components panel:
Add instructions for setting up the component in the Components panel or in a dialog box (depending on the extension for which the steps are implemented). The instructions are also known as setup steps, and appear as interactive numbered steps. Make sure that check marks appear next to any steps the user has completed.
