Hi, This specifically Rails question is off-topic here. Try the Rails list: http://lists.rubyonrails.org/mailman/listinfo/rails You'll get better answers for Rails questions like this there. In direct answer to your question, you probably want to toggle the display property of the children between "none" and "" (default). The JavascriptHelper might be of use: http://api.rubyonrails.com/classes/ActionView/Helpers/JavaScriptHelper.html Cheers, Dave
