Yetii stands for Yet (E)Another JavaScript Tab Interface Implementation.

There are plenty of DHTML tabs scripts out there but most of them are either poorly coded, library/framework dependend or bloated with unnecessary functionality. So I`ve decided to come up with this simple, yet functional tab interface implementation.

Features

• extremely lightweight, object-oriented code
• gracefull degradation in browsers without JavaScript
• you can have many independend tab interfaces on a single page
• you can specify initial tab
• you can customize default class names
• you can turn on automatic tabs rotation (available in two modes)
• you can add next/previous navigation
• you can nest one tab interface inside another
• you can manually invoke tab showing method
• you can define custom function to run after certain tab is clicked
• you can define custom function to run when user leaves certain tab
• you can link to certain tab on page A from page B via URL parameter
• you can turn on tab persistence feature, so the most recently clicked tab is stored inside a cookie and remembered between page refresh
