Malihu jQuery Custom Scrollbar with Select 2

Question

Scrollbar shows only on first opening and no more. What I did wrong?

$('.select').on('select2:open', function () {
    function showScroll() {
        $('.select2-results__options').mCustomScrollbar();
    }
    setTimeout(showScroll, 1);
});

Answer 1

I found a solution:

$('.select').on('select2:open', function () {
    $('.select__dropdown .select2-results__options').mCustomScrollbar('destroy');
    $('.select__dropdown .select2-results__options').mCustomScrollbar('update');
    setTimeout(function() {
        $('.select__dropdown .select2-results__options').mCustomScrollbar({
            axis: 'y',
            scrollbarPosition: 'inside',
            advanced:{
                updateOnContentResize: true
            },
            live: true
        });
    }, 0);
});
