To some extent ,i do know that we can not use a tree  the component in ICEfaces and Woodstock to create a right to left tree nodes(like the using Farsi(Persian) text in tree nodes,or another right to left language, in these cases the node icon must be in right).Does it true for tree component of richfaces  ?
I have seen the http://livedemo. exadel.com/ richfaces- demo/richfaces/ tree.jsf ,but there, i did not find anything.

Is there another framework that have a tree component the same as a tree in Richface ,supports client swichtype and of course supports right to left languages?
