Question

我有一个简单的下拉菜单，如果子菜单项大或小，我希望子菜单的宽度占用所需的空间。

现在，它包裹在第二行..见

我试过宽度：自动;不起作用。

CSS：

.dropdown {
     position: relative;
    display: inline-block;
    margin:0 12px;
}

.dropdown-content {
    display: none;
    position: absolute;
    background:white;
    width:auto;

    padding: 12px 16px;
    z-index: 1;

}

.dropdown:hover .dropdown-content {
    display: block;
}

.subm{margin:12px 0;}

我的HTML：

<div class="dropdown">
    <span>PRODUCT INFO</span>
    <div class="dropdown-content">
        <div class="subm"><a class="menulink" href="#ingredients">INGREDIENTS</a></div>
        <div class="subm"><a class="menulink subm" href="#ingredients">CUSTOMER REVIEWS</a></div>
        <div class="subm"><a class="menulink subm" href="#ingredients">NUTRITIONAL FACTS</a></div>
        <div class="subm"><a class="menulink subm" href="#ingredients">ORDER NOW</a></div>
    </div>
</div>

Answer 2

尝试将position: relative用于.dropdown。请参阅下面的代码：

＆＃13;

.dropdown {
  position: relative;
  display: inline-block;
  margin: 0 12px;
}

.dropdown-content {
  display: none;
  position: relative;
  background: white;
  width: auto;
  padding: 12px 16px;
  z-index: 1;
}

.dropdown:hover .dropdown-content {
  display: block;
}

.subm {
  margin: 12px 0;
}

＆＃13;

<div class="dropdown">
  <span>PRODUCT INFO</span>
  <div class="dropdown-content">
    <div class="subm"><a class="menulink" href="#ingredients">INGREDIENTS</a></div>
    <div class="subm"><a class="menulink subm" href="#ingredients">CUSTOMER REVIEWS</a></div>
    <div class="subm"><a class="menulink subm" href="#ingredients">NUTRITIONAL FACTS</a></div>
    <div class="subm"><a class="menulink subm" href="#ingredients">ORDER NOW</a></div>
  </div>
</div>

Answer 3

只需从position:absolute样式中移除.dropdown-content

即可

.dropdown {
  position: relative;
  display: inline-block;
  margin: 0 12px;
}
.dropdown-content {
  display: none;
  background: white;
  padding: 12px 16px;
  z-index: 1;
}
.dropdown:hover .dropdown-content {
  display: block;
}
.subm {
  margin: 12px 0;
}

<div class="dropdown">
  <span>PRODUCT INFO</span>
  <div class="dropdown-content">
    <div class="subm"><a class="menulink" href="#ingredients">INGREDIENTS</a>
    </div>
    <div class="subm"><a class="menulink subm" href="#ingredients">CUSTOMER REVIEWS</a>
    </div>
    <div class="subm"><a class="menulink subm" href="#ingredients">NUTRITIONAL FACTS</a>
    </div>
    <div class="subm"><a class="menulink subm" href="#ingredients">ORDER NOW</a>
    </div>
  </div>
</div>
