The Slidable Insights module works almost the same as the Insights one, only in a slidable fashion. They will take as much vertical space as the taller module needs according to which module is shown every time.
You can use all the layout options you would set up for the Insights module. In addition, select whether to use a cool numbered slide navigation or an elegan arrows one.
Please note: the modules availability and their specific settings depend on each theme, not all themes include the same modules with the same settings.
