Avanti comes with a modified Slideshow widget which works perfectly inside the theme's header layout position.
With the Widgetkit 2.5 release we have added the Slideshow Panel. Avanti uses a slightly modified version perfectly fitting for any portfolio, case study or product presentation.
For Avanti we have added a modified grid widget to customize our output, especially the one we can not control at all, like WordPress/Joomla system content. We have added a truncate option for the title and the content which makes it easier to control the data output and height.
