Hi Bro,

Can you please let me know the responsive feature in this plugin? Because, currently it's needed for me!

Thanks a lot for this great plugin! 👍

Thanks, mate! Mail sent! :)

How can a make this responsive ? Like this site https://getbase.com/why-base/ ? I'd be grateful if you please give me any solution.

Read above.

Thanks for your replay.. I've solved the responsive issue using below code:

<script type="text/javascript">
 $(document).ready(function() {
        if ($(window).width() <= 767) {

            $('.ms-right .ms-section').unwrap().appendTo('.ms-left');

            var ul = $('.ms-left').find('.ms-section').sort((a, b) => {
              return $(a).data('id') - $(b).data('id')
            })

            $('.ms-left').empty().append(ul);

        } else {
            $('#myContainer').multiscroll({
                sectionsColor: ['#1bbc9b', '#4BBFC3', '#7BAABE'],
                menu: '#menu',
                navigation: true,
                navigationTooltips: ['One', 'Two', 'Three'],
                loopBottom: true,
                loopTop: true
            });
        }
    });
</script>

A new extension provides this feature! Check the Responsive Expand extension

Is there any possibilities that this multiscroll and fullpage can be merge?

No idea. I never tried myself :)
