我正在使用jquery mCustomScrollbar和niceselect插件。当我通过单击扩展niceselect下拉列表时，mCustomScrollbar未更新。我认为，这是由于下拉列表的绝对位置而发生的。但是我该如何解决呢？
这是jsfiddle链接：

var $ = jQuery.noConflict(),
wrapper = $('.wrapper');
$('select').niceSelect();
wrapper.mCustomScrollbar();
最佳答案
当我尝试您的提琴手时，问题就在那里。
但是，当我将此代码复制到HTML中时，它似乎正在工作。
将其发布为答案，因为这是共享代码的简便方法。
将此复制到html并尝试。我认为这是提琴手的局限性。让我们知道结果。
