PrimeFaces 3.2 development has started along with 3.1.1 maintenance in parallel. The first feature of 3.2 we have added is BlockUI component that can block a particular content. Usage is quite simple thanks to the special ajax integration, also client side api is provided if you need to write extensions or customize it.
The component is inspired by the blockui jquery plugin, we have our own implementation instead of using that plugin but the idea is pretty much the same.
Checkout PrimeFaces Labs to see BlockUI in action! It is theme integrated as usual so don’t forget to try with different themes
