Blue Sea Systems' Panel Wizard
http://panelwizard.bluesea.comThe Panel Wizard is an online tool created for Blue Sea Systems that allows customers to create and order custom electrical panels online. It is built with Ruby on Rails with a PostgreSQL database.
Customers can easily drag and drop the modules from groups into any size panel they choose. They can then click on individual modules to customize the components within a given module. The price is updated as they construct their panel as well as a high resolution image of their panel.
