Contents: Creating mashups : Mashup Center 2.0
Mashup Center provides a palette with a default set of categories and widgets. You can make changes to the default palette to create a more personalized workspace. For example, you can add and remove widgets, add new categories, customize widgets, and more. You can drag widgets directly from the palette to your pages.
The widgets that are available in your palette can come from various sources. For example, Mashup Center provides a set of default widgets and categories that you can use as you build mashup applications. Your administrator can also configure a global palette for you and others to share. You can also add widgets from the catalog or build your own widgets using the widget builder.
