User selected item of Drop Down

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"] ]
