I created a responsive navigation menu with a tutorial in Hongkiat. http://www.hongkiat.com/blog/responsive-web-nav/
In that tutorial there is no sub menu items. But I want to add a submenu.
This is the demo I created in JSfiddle. http://jsfiddle.net/viveknath322/3AHTg/1/
In that demo I want to add submenu in Tools menu. Its very helpful if you modify that code in Jsfiddle.
Any help will be appreciable.
