i like the Navigation style in the demo application (http://demo.vaadin.com/sampler/#). While searching this forum I found a post 5 month ago that the source code isn’t available due to license problems. But maybe someone can give me a hint which addon or widget I have to use to reproduce this navigation style.
can’t help you much I’m afraid, but from what I know the navigation circle is a custom GWT widget written for the purpose and the effects are done using CSS transforms, which you can probably see a bit of by examining the CSS styles of the sampler application. This is also why the animations don’t work on IE8/9.
