SliderNav is a plugin that lets you add dynamic, sliding content using a vertical navigation bar (index). It's made mainly for alphabetical listings but can be used with anything, though longer words look a little awkward (see example 2).
For more detailed instructions and customization options, see the article on DevGrow (or view the plugin source).
This plugin was created by Monjurul Dolon, author of DevGrow, a blog for web developers and designers. Inspiration for this effect came from a new technology blog called Techi - be sure to support them as well!
