导航下拉菜单显示太左

Question

我一直在努力解决这个问题，但无法弄清楚我缺少什么。我希望下拉列表显示在其父项的正下方。该列表显示，但全部都向左移动，并强制剩余的导航项目下拉到另一行。我已经包含了当前外观的 sn-p 和 what I want it to look like 的图像。另外，我一直在试图弄清楚如何使用下拉列表将 fa fa-caret 添加到导航项目中。请帮忙！

Answer 1

您可以通过首先将 div.list 元素设置为绝对定位来实现此目的。 'display:block' 属性将所有其他内容推送到下一行，因为块元素占用了空间。

正如您现在看到的，列表不再向下推送内容，但现在它未与正确的导航项对齐。我们还将添加一个 left:0 以便 div.list 位于父属性的左侧。

现在父属性需要一个相对位置，以便子元素上的 left:0 相对于父元素定位。

.dropdown:hover .list {
   display: block;
   position: absolute;
   left: 0;
}

.navbar li {
   border-left: solid 2px #000000;
   display: inline;
   list-style-type: none;
   width: 800px;
   padding: 0;
   position: relative;
}

Answer 2

您的 CSS 代码的问题是，您错过了将 position: relative 和 position: absolute 添加到 .dropdown 和 .list 选择器，这是创建下拉菜单所必需的。试试这个代码。

.navbar {
  background: linear-gradient(#9E0A0C, #EBEBEB);
  padding: 10px;
  border-top: solid 1px #000000;
}

.navbar a {
  text-decoration: none;
  color: #ffffff;
  font-weight: bolder;
  font-size: 20px;
  text-transform: uppercase;
  padding: 3px 5px;
  margin: auto;
  /*float: left;  may need to be removed to show borders*/
  display: inline;
}

.navbar ul {
  padding: 0;
  margin-top: 0;
  width: auto;
}

.navbar li {
  border-left: solid 2px #000000;
  display: inline;
  list-style-type: none;
  width: 800px;
  padding: 0;
}

.navbar a:active {
  background-color: #000000;
}

.navbar li:hover > a {
  background-color: #ddd;
  color: black;
}

li:first-child {
  border-left: none;
}

.dropdown {
  display: block;
  overflow: hidden;
  position: relative;
  /*float: left;*/
}

.list {
  display: none;
  min-width: 50px;
  max-width: 150px;
  z-index: 2;
  box-shadow: 0 8px 16px 0 #e7e7e7;
  background: #050243;
  position: absolute;
  left: 0;
  top: 100%;
}

.list a {
  color: #000000;
  float: none;
  font-size: 14px;
  text-decoration: none;
  display: block;
  text-align: left;
  background-color: #B6B6B6;
  columns: 2;
}

.list a:hover {
  background-color: #EEEEEE;
}

.dropdown:hover .list {
  display: block;
}

form {
  float: right;
  padding: 0px;
  margin: 0;
  overflow: auto;
}

input {
  border: solid 1px #000000;
  background-image: url(pics/search.png);
  background-repeat: no-repeat;
  background-position: center right;
  background-size: 15px;
  border-radius: 5px;
  padding: 5px 2px;
  width: 250px;
}
