Click Extras provides a library of additional controls and components which are outside of the core Click framework.

Click Extras are packaged as a separated JAR which you can deploy with your application. Extra packages include:

• Cayenne - provides Cayenne data aware controls
• Control - provides extra controls
• Filter - provides GZIP compression Filter
• Hibernate - provides Hibernate data aware controls
• Panel - provides Page Panel containers
• Spring - provides Spring integration SpringClickServlet

Please Note the Cayenne, Hibernate and Spring dependencies are only required if you use these particular features. For example if you are using Hibernate for your persistence framework, the CayenneForm control will not cause any issues as this class would never be loaded by your application.

For a detailed list of dependencies please see Extras Dependencies.
