Rails: How do I display flash[:notice] modally

I'm looking for a way to recreate the effect used by stackoverflow to display information about badges awarded etc to users, except I want to use the effect to display my fl开发者_开发问答ash messages.

In case it's not clear, I'm talking about the way site updates appear at the top of the browser window and stack there until the user clicks the X button although I won't mind if the messages disappear when the user refreshes the page.

I know this is not technically 'modal'.

Does anyone have any experience of doing this in rails?

use this in your view

<%= render :partial => 'my_custom_flash', :flash => flash %>

and in _my_custom_flash.html.erb

<div id='flash-notice'><%= flash[:notice] %> <%= link_to_function 'Close', visual_effect(:fade, 'flash-notice' %></div>

and you have to set your CSS to make #flash-notice position absolute, with parameters like top:0 and width:100% to make it appear on the top.

I didn't test this code, but it would be my initial approach to solve this
