Showing/Hiding Content-Type Fields Based On User I have a content-type that has many fields for different translations. How do I set it up in a way that it shows the translation field based on user selection only. I mean user selects his/her language, then only that content-field appears on the post.

Appreciated...
Yeah you could do that as well, though if you have lot of data hidding things on the server side would be better. You could just override the node template page, with something like :
node--nodeType.tpl.php, then in the variables of that page you will have your node with all its Fields available, you can then do a simple check (cookie or sessions) to render appropriate language.
