我正在尝试修复此导航。我想将“动物”（羊驼，水牛等）上的下拉菜单分为2或3个部分，因此列表不会太长。
这里是代码：
@charset "utf-8";
body {
font: 100%/1.4 Verdana, Arial, Helvetica, sans-serif;
background: #4E5869;
margin: 0;
padding: 0;
color: #000;
}
.wrapper {
width: 90%;
max-width: 1260px;
/* a max-width may be desirable to keep this layout from getting too wide on a large monitor. This keeps line length more readable. IE6 does not respect this declaration. */
min-width: 480px;
/* a min-width may be desirable to keep this layout from getting too narrow. This keeps line length more readable in the side columns. IE6 does not respect this declaration. */
background: #FFF;
margin: 0 auto;
/* the auto value on the sides, coupled with the width, centers the layout. It is not needed if you set the .container's width to 100%. */
}
/*First remove all default margins and padding*/

ul,

</html>我想做的就是保留这种设计，但是将动物部分放下2或3列，这样就不会太长了。现在很长。我不确定这是否会有所作为，但是此导航将在php页面上。
可以看到当前布局here。
仅需注意，这只是一个临时站点，用于解决问题而不中断将要使用它的站点。
只需为此创建一个特定的CSS：
ul.cols-2 {
columns: 2;
-webkit-columns: 2;
-moz-columns: 2;
}
并添加此类，如下所示：
<ul class="cols-2" >
<li><a href="alpacas.php">Alpacas</a></li>
<li><a href="buffalo.php">Buffalo</a></li>
<li><a href="chickens.php">Chickens</a></li>
