There are not, but you could easily adapt the lightslider plugin to use another slider script. Better yet create a new plugin based on lightslider. Really there’s not much to it. It’s mainly adding a CSS file, a JS file, and a Twig template to render the output.
@rhukster Thanks for sharing. I guess I am not clear enough yet on if “everything” has to be truned into a Grav plug-in or how I can generically included any JS lib without making a plug-in. I will use the lightslider code to see if I can make my first plugin using owl. Thanks for your response - very helpful.
