I have this list and what I want to do is to have a link that allows the  
user to add something to this list. So I have a form with the :update  
option, but I want the update to happen at the end of this div that I  
have set aside for this list. I don’t remember how to use :update and  
tell it to add at the end of the list. Or is it done with render? Can  
anyone help, Thanks,

If you use :update in your link\_to\_remote or remote\_form\_for, you need  
to redraw the entire list. If you want to just add something to the  
bottom of the list, you leave off :update and do an RJS response  
(either a .rjs template or render :update do |page| … end)
