Our templates feature multiple styles that can be selected from the template manager, but you can also change the styles per menu item!
To create a style switcher menu like in our demos all you need to do is create a new menu item using the Joomla / System Links / External URL menu type and in the URL field add &xtcstyle=style1 or whichever style you want to display. To add this to a Component based URL you will need to first copy the component URL and then add that as your External menu type URL and append the &xtcstyle=style1 at the end.
