In my view I have

form.select( :child, @children.map { | u | [0], u[1] }, { },  
{ :onchange = remote\_function(  
:url =\> {:action =\> “rjs\_call\_here”},  
:with =\> " ‘child\_picked=’ +  
escape(value)" ) } )

Everything works well with ajax and drop down menu.

My problem is that when the user hits submit I want the same drop down  
menu as above displayed but this time with  
the user selection showing.

On thought is to check in the view to see if a the user has made a  
selection and then show a different drop down.

I am not sure of what method to use in order to do this.

In other words I need to reflect user choice of the drop down after  
the user has clicked on the submit button.

If things are not clear.

@children is set in the controller ie:

@children = [[“Select Child”, “”], [“John”, “1”], [“Mary”, “2”],  
[“Fred”, “3”] ]
