CSS響應下拉菜單 - 拆分爲2列

Question

我已經查看了所有在這裏的支持，並嘗試了很多不同的方式來將這個CSS下拉菜單分成2列，因爲我有很多條目將nav列表拉伸到折。

即使菜單是響應式的，我只需要兩列在擴展時工作，而不是在移動瀏覽縮小時（這方面很好）。我也使用jQuery腳本。

我還沒有成功使用我的代碼的任何調整。任何人都有關於如何將此下拉菜單拆分爲2個並排列的建議？

這裏的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> 

這裏的CSS：

    #cssmenu ul ul li.has-sub > a::after { 
    display: none;

} 

這裏是jQuery的：

(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); 

Answer 1

不是一個完美的解決方案，但我在兩列得到了這個工作屏幕尺寸超過480px寬。

@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; 
    } 
}
