jquery - CSS 响应式下拉菜单 - 分成两列

Question

我查看了此处的所有支持，并尝试了许多不同的方法将此 CSS 下拉菜单拆分为 2 列，因为我有许多条目将导航列表向下延伸到折叠下方。

即使菜单是响应式的，我只需要两列在展开时工作，而不是在移动浏览时收缩(这方面很好)。我也在使用 jQuery 脚本。

我还没有成功地对我的代码进行任何调整。有人对我如何将此下拉列表拆分为 2 个并排的列有任何建议吗？

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($){
$(document).ready(function(){

$('#cssmenu').prepend('<div id="menu-button">Menu</div>');
  $('#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:

$(function() {
  if ($(window).width() <= 768) {
    $('.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 {
    $('.sub-menu').show();
  }
});
