通常和z-index一起在我的带有滑块的项目中始终有效.不要忘记在滑块的之后呈现菜单，这样就迫使它位于顶部.

Usually position: absolute; along with z-index works always in my projects with sliders. Do not forget to render the menu after the slider so it is forced to sit on top.

这是我在Chrome中编辑HTML时所做的事情:

Here is what I did when I edited your HTML in Chrome:

<div class="main">
...
 your slider code
...
</div>

<!--See the added inline styles -->

<div class="wrapper_menu menu_dark_theme" style="position: absolute; margin-top: -1200px; z-index: 9999;">
   <ul class="menu menu_takeflight">...</ul>
</div>
