CSS响应下拉菜单 - 分为2列

Question

我已经查看了这里的所有支持，并尝试了许多不同的方法将这个CSS下拉菜单拆分为2列，因为我有许多条目可以将导航列表向下拉伸。

即使菜单是响应式的，我只需要在扩展时使用两列，而不是在移动浏览时收缩（这方面很好）。我也在使用jQuery脚本。

我还没有成功使用我的代码的任何调整。有人建议我如何将这个下拉列表分成两个并排的列？

这是HTML：

<div id='cssmenu' class='align-center'>
<ul>
 <li><a href='index.html'>Home</a></li>
 <li class='has-sub'><a href='equipment.html'>Equipment</a>
   <ul>
     <li><a href='#'>Automotive</a></li>
     <li><a href='#'>Building Equip.</a></li>
     <li><a href='#'>Concrete Tools</a></li>
     <li><a href='#'>Drills</a></li>
     <li><a href='#'>Generators</a></li>
     <li><a href='#'>Heaters</a></li>
     <li><a href='#'>Household Equip.</a></li>
     <li><a href='#'>Ladders</a></li>
     <li><a href='#'>Painting</a></li>
     <li><a href='#'>Party / Canopy</a></li>
     <li><a href='#'>Plumbing</a></li>
     <li><a href='#'>Pumps</a></li>
     <li><a href='#'>Sanders</a></li>
     <li><a href='#'>Saws</a></li>
     <li><a href='#'>Stage</a></li>
     <li><a href='#'>Table & Chairs</a></li>
     <li><a href='#'>Trailers</a></li>
     <li><a href='#'>Trenchers</a></li>
     <li><a href='#'>Garden & Lawn Care</a></li>
     <li><a href='#'>Miscellaneous</a></li>
   </ul>
 </li>
 <li><a href='concrete.html'>Concrete</a></li>
 <li><a href='gravel.html'>Gravel</a></li>
 <li><a href='propane.html'>Propane</a></li>
</ul>
</div>

这是CSS：

这是jQuery：

(function($){

  $('#cssmenu #menu-button').on('click', function(){
    var menu = $(this).next('ul');
    if (menu.hasClass('open')) {
      menu.removeClass('open');
    } else {
      menu.addClass('open');
    }
});

});
})(jQuery);

这是HTML：

    $('.sub-menu').hide();
    $('.has-ancho > a').on('click', function() {
      $(this).parent('.has-ancho').toggleClass('open').find('i:eq(0)').toggleClass('fa-rotate-180');
      if (!$(this).parent('.has-ancho').hasClass('open')) {
        $(this).parent('.has-ancho').find('.has-ancho').removeClass('open');
      }
    });
  } else {

Answer 2

这不是一个优雅的解决方案，但我在两列中工作，屏幕尺寸超过480px宽。

@media only screen and (min-width: 480px) {
    #cssmenu > ul > li > ul > div {
        width: 200%;
    }
    #cssmenu > ul > li > ul > div > li {
        display: inline-block;
        width: 49%;
        white-space: nowrap;
    }
}
