jquery Chosen and mCustomScrollbar not working properly together - jquery-chosen

Question

I use jquery Chosen together with malihu's plugin mCustomScrollbar and
I found it not compatible.
I want to apply the scrollbar on chosen result and its not working. Here is my working fiddle to see my work.
HTML:
$(function() {
$('select.select').chosen({
disable_search_threshold: 10,
width: "50%"
});
//$('.chosen-results').mouseenter(function() {
$('.chosen-results').mCustomScrollbar({
theme: "dark-3"
});
//});
});
.select {
max-height: 100px;
}

<option value="">Select</option>
<option value="aaa">aaa</option>
<option value="bbb">bbb</option>
<option value="ccc">ccc</option>
<option value="ddd">ddd</option>
<option value="eee">eee</option>
<option value="fff">fff</option>
</select>

Answer 1

You have to initialize the mCustomScrollbar when it is visible.
$(function() {
$('select.select').chosen({
disable_search_threshold: 5,
width: '50%'
});
$('select.select').on('chosen:showing_dropdown', function() {
$('.chosen-results:visible').mCustomScrollbar({
theme: 'minimal-dark'
});
});
$('select.select').on('chosen:hiding_dropdown', function() {
if($(".chosen-results").length) {
$('.chosen-results').mCustomScrollbar('destroy');
}
});
});
.chosen-drop .chosen-results {
max-height: 100px !important;
}
