I mean http://www.arcgis.com/home/item.html?id=9b6280a6bfb0430f8d1ebc969276b109
of nliu that is very useful. Recently I found how to show the tree of TOC in right to left mode.
Firstly define
div id="tocDiv" dir="rtl"
where tocDiv is a tag you would attach TOC to.
Secondly in source code Toc.js of tOC widget replace
paddingLeft by paddingRight
(there are 2 such places)
That's all
