The user interface has been simplified in Dreamweaver CC and later. As a result, you may not find some of the options described in this article in Dreamweaver CC and later. For more information, see this article.
You can make your own personal selection of web widgets available in Dreamweaver by using the Adobe Widget Browser—an AIR application that lets you browse, configure, and preview widgets using a visual interface.
You can also add a web widget to a Dreamweaver page (CS5.5 and later) by doing the following:
In the Widget Browser, navigate to My Widgets.
Select the widget you want to add.
Click and hold the Drag and Drop in Dreamweaver icon at the upper left corner of the Live View tab. Drag the widget to Dreamweaver into Design view (Windows) or Design or Code view (Macintosh OS).
