带按钮和“宽度：自动”列表的水平滚动 UL

正如标题所示，我正在尝试创建一个水平可滚动的<ul> with <li> with width:auto并带有上一个和下一个按钮，清楚地带有overflow:hidden。 关于如何使用 jquery 管理它有什么建议吗？ 这是我准备好的代码......

JSFiddle

HTML:

<div id="wrapper">
  <span class="arrow">&lt;</span>
  <span class="arrow">&gt;</span>
  <ul id="nav">
    <li>Abbaiare</li>
    <li>Bolle</li>
    <li>Cantante</li>
    <li>Domodossola</li>
    <li>Elefante</li>
    <li>Giovanni</li>
    <li>Hotel</li>
    <li>Inti</li>
    <li>Montagna</li>
    <li>Nave</li>
  </ul>
</div>

CSS:

* {
  margin:0;
  padding:0;
}
#wrapper {
  width:calc(100% - 120px);
  height:60px;
  background-color:#dbdbdb;
  padding:0 60px;
  margin-top:60px;
  font-family:helvetica;
  overflow:hidden;
  position:relative;
  z-index:99; 
}
.arrow {
  display:block;
  width:60px;
  height:60px;
  line-height:60px;
  text-align:center;
  background-color:#cccccc;
  font-weight:bold;
  cursor:pointer;
  position:absolute;
  top:0;
  z-index:101;
}
.arrow:first-of-type {
  left:0;
}
.arrow:nth-of-type(2) {
  right:0; 
}
#nav {
  width:auto;
  height:60px;
  overflow:hidden;
  list-style-type:none;
  white-space:nowrap;
  transition:2.0s;
}
#nav li {
  display:inline-block;
  height:60px;
  line-height:60px;
  font-size:13px;
  padding:0 30px;
}

你可以简单地使用bxSlider无需重新发明轮子。要使您的代码正常工作，您只需添加：

$(function () {
  $('#nav').bxSlider({
    pager: false,
    minSlides: 3,
    maxSlides: 3,
    slideWidth: 150,
    slideMargin: 25
  });
});

#wrapper {
  margin: auto;
}
.bx-viewport {
  height: 50px !important;
  padding: 0 30px;
  box-sizing: border-box;
  text-align: center;
}
