Question

我创建了一个表单，我有一个侧面导航栏。在这种情况下，所有<li>元素的放置方式使得两个<li>落在一行中。现在，问题是，只要<li>元素的文本增加，它就会影响其他<li>元素。这就是我尝试过的方式：

body {
  overflow-x: hidden;
}
    
    /* Toggle Styles */
    
#wrapper {
  padding-left: 0;
  -webkit-transition: all 0.5s ease;
  -moz-transition: all 0.5s ease;
  -o-transition: all 0.5s ease;
  transition: all 0.5s ease;
}
    
#wrapper.toggled {
  padding-left: 250px;
}
    
#sidebar-wrapper {
  z-index: 1000;
  position: fixed;
  left: 250px;
  width: 0;
  height: 100%;
  margin-left: -250px;
  overflow-y: auto;
  background: #000;
  -webkit-transition: all 0.5s ease;
  -moz-transition: all 0.5s ease;
  -o-transition: all 0.5s ease;
  transition: all 0.5s ease;
}
    
#wrapper.toggled #sidebar-wrapper {
  width: 250px;
}
    
#page-content-wrapper {
  width: 100%;
  position: absolute;
  padding: 15px;
}
    
#wrapper.toggled #page-content-wrapper {
  position: absolute;
  margin-right: -250px;
}
    
  /* Sidebar Styles */
    
.sidebar-nav {
  position: absolute;
  top: 0;
  width: 120px;
  margin: 0;
  padding: 0;
  list-style: none;
  text-indent: -2em;
}
    
.sidebar-nav li {
  text-indent: 20px;
  line-height: 40px;
}
    
.sidebar-nav li a {
  display: block;
  text-decoration: none;
  color: #999999;
}
    
.sidebar-nav li a:hover {
  text-decoration: none;
  color: #fff;
  background: rgba(255,255,255,0.2);
}
    
.sidebar-nav li a:active,
.sidebar-nav li a:focus {
  text-decoration: none;
}
    
.sidebar-nav > .sidebar-brand {
  height: 65px;
  font-size: 18px;
  line-height: 60px;
}
    
.sidebar-nav > .sidebar-brand a {
  color: #999999;
}
    
.sidebar-nav > .sidebar-brand a:hover {
  color: #fff;
  background: none;
}
    
.sidebar-nav_wrapper    {
  float:left;
  margin-left:5px;
}

<div id="sidebar-wrapper">
  <div class="sidebar-nav_wrapper">
    <h4 class="sidebar-brand">Select Field Type</h4>
    <ul class="sidebar-nav" style="margin-top: 40px;">
    	
      <li><a href="#" data-toggle="modal" data-target="#SingleLine_Modal">Single Line</a></li>
      <li><a href="#" data-toggle="modal" data-target="#PickList_Modal">Pick List</a></li>
      <li><a href="#" data-toggle="modal" data-target="#MultiSelect_Modal">Multi Select</a></li>
      <li><a href="#" data-toggle="modal" data-target="#MultiLine_Modal">Multi Line</a></li>
      <li><a href="#" data-toggle="modal" data-target="#Email_Modal">Email</a></li>
      <li><a href="#" data-toggle="modal" data-target="#Phone_Modal">Phone Number</a></li>
      <li><a href="#" data-toggle="modal" data-target="#Mobile_Modal">Mobile Number</a></li>
    </ul>
  </div>
  <div class="sidebar-nav_wrapper">
    <ul class="sidebar-nav" style="margin-top: 40px; margin-left: -20px;">
      <li><a href="#" data-toggle="modal" data-target="#Date_Modal">Date</a></li>
      <li><a href="#" data-toggle="modal" data-target="#Time_Modal">Time</a></li>
      <li><a href="#" data-toggle="modal" data-target="#DateTime_Modal">Date-Time</a></li>
      <li><a href="#" data-toggle="modal" data-target="#CheckBox_Modal">Checkbox</a></li>
      <li><a href="#" data-toggle="modal" data-target="#Radio_Modal">Radio</a></li>
      <li><a href="#" data-toggle="modal" data-target="#Decimal_Modal">Decimal</a></li>
      <li><a href="#" data-toggle="modal" data-target="#Number_Modal">Number</a></li>
      <li><a href="#" data-toggle="modal" data-target="#AutoNumber_Modal">Auto Number</a></li>
  </div>
</div>

我想要的是，每当<li>的文字大小增加时，外面只显示几个字母，..成功。我提供了我的CSS和HTML。我不知道要纠正什么，在哪里纠正。那么，有人可以帮助我实现我想要的吗？

Answer 1

您可以使用white-space: nowrap;阻止文字换行到第二行，并text-overflow: ellipsis;显示...而不是溢出的文字部分

Answer 2

您可以使用此代码

你必须增加导航栏的宽度。这就是我所做的。

我根据列表元素中文本的长度引入了span元素。
如果长度大于12，则在锚标记之后和字符串的第一部分之后创建span标记。
锚标记中的文字将是＆＃34; ...＆＃34;。如果我们想要查看额外的文字，您必须点击＆＃34; ...＆＃34;部分和文本的额外部分将与前一个文本一起查看。
您可以调整额外文字的代码以显示＆＃34; onhover＆＃34;或任何其他事件。
您还可以更改文本的字数限制，之后必须显示范围

在`<li>`元素
