Dynamic tree component

[ruchi thakur]

Hello I want to build a tree in jsf. Here i want server side toggling of the tree nodes. ie; the tree should be even driven. Thus the requirement comes down to
1) Server side toggling - only the expanded node should be refreshed and not the entitre jsf page
2) When a node is selected, the content in the middle/body tile of the jsf page should be refreshed. Again this data will be coming from server based on the tree selected, but i dont want entire jsf to be refreshed

Do i have any such tree component?
Also i want that if the javascipt is disabled even then this should work. I think ajax4jsf does not use javascript. But am not sure how can i combine it with a tree component. Please suggest.
I have heard of various tree components like trinidada, tomhawk but am not sure how to use them.
Regards,
