YUI Library: Index of Official Examples

Every YUI Library component ships with a series of 276 examples that illustrate its implementation. These examples can serve as starting points for your exploration of YUI, as code snippets to get you started in your own programming, or simply as an inspiration as to how various interaction patterns can be enabled in the web browser via YUI.

The navigation controls on the left side of this page allow you to explore these examples component-by-component; on this page you'll find the full index of library examples with a link to and short description of each one.
