In current implementation of RichFaces Demo left menu is reloaded always after clicking on some item. Would you make it unreloaded like as IceFaces Demo http://component-showcase.icefaces.org/component-showcase/ ?? Is it real possibly with RichFaces??
It is possible, but we would not do it on this demo.
The demo has been designed to be bookmarkable on the level of different components.
As an example, try to send a direct link to the demo of Calendar from the showcase you mentioned above.
This is a direct link to rich:calendar :
