Dear Alvarix,
Please open default.php file (yoursite/templates/sj_joomla3/html/mod_carousel/default.php) add the script following:
<script type="text/javascript">
jQuery(document).ready(function($){
setInterval(function(){
$('#myCarousel .carousel-control.right').trigger('click');
},5000);
});
</script>
before the code :
<?php }else{ echo JText::_('Has no content to show!');}?>
If you want add class, you can add in 'Module Class Suffix' in module manager, example: ' blank' =>' blank your_class'
Thanks
