Because more and more websites are changing to responsive layouts I will be looking into ways of making multi-level menus that will respond to various screen sizes and also adapt for use on tablets and smartphones using touch screens
So this droplist menu will change from a maximum of four columns in the droplist when viewed on monitors with a resolution greater than 1000px down to a single column for smartphones with a resolution of less than 480px.
For IE7+, IE10/IE11 touch screens, Firefox, Opera, Safari, Chrome, iOS, Android OS, tablets, smartphones including Windows wp8, touch screens etc. All the radio input coding is for Windows wp8 smartphones.
