html - 绝对定位的div不能根据内容自动调整

Question

我正在使用悬停下拉菜单进行导航，一切正常，但问题在于下拉菜单，下拉菜单不会根据内容/文本增加。我希望下拉菜单根据其内容采用宽度。

.navigation {
  width: 100%;
  float: left;
  background: #008271;
  min-height: 50px;
  font-family: segoe ui;
  padding: 0 30px;
}
.navigation,
.navigation * {
  box-sizing: border-box;
}
.navigation ul {
  padding: 0;
  margin: 0;
  list-style: none;
}
.navigation .nav-right {
  float: right;
}
.navigation > ul > li {
  display: block;
  float: left;
  position: relative;
}
.navigation > ul > li > a {
  display: block;
  color: #fff;
  height: 50px;
  line-height: 50px;
  text-align: center;
  padding: 0 15px;
  font-size: 15px;
}
.navigation > ul > li.drop-menu:hover > a,
.navigation > ul > li.drop-menu > a:hover {
  background: #01675a;
}
.navigation .sub-menu {
  display: none
}
.navigation > ul > li:hover .sub-menu {
  width: 100%;
  display: block;
  position: absolute;
  top: 50px;
  background: #fff;
  min-width: 160px;
  right: 0;
  border: 1px solid rgba(0, 0, 0, .15);
  box-shadow: 0 6px 12px rgba(0, 0, 0, .17);
  padding: 5px 0;
  -webkit-background-clip: padding-box;
  background-clip: padding-box;
}
.sub-menu > li > a {
  display: block;
  padding: 5px 15px;
  color: #333;
  white-space: nowrap;
  font-size: 14px;
}
.sub-menu > li > a:hover {
  background: #f5f5f5;
}
.caret {
  display: inline-block;
  width: 0;
  height: 0;
  margin-left: 2px;
  vertical-align: middle;
  border-top: 4px dashed;
  border-top: 4px solid\9;
  border-right: 4px solid transparent;
  border-left: 4px solid transparent;
}
.nav-left > li > a {
  font-size: 24px!important;
  font-weight: 300;
}

<div class="navigation">
  <ul class="nav-right">
    <li class="drop-menu">
      <a href="#">Teams <span class="caret"></span></a>
      <ul class="sub-menu">
        <li><a href="#">Team 1</a>
        </li>
      </ul>
    </li>
    <li class="drop-menu">
      <a href="#">Communities <span class="caret"></span></a>
      <ul class="sub-menu">
        <li><a href="#">Communities 1</a>
        </li>
        <li><a href="#">Communities 2 and much more content</a>
        </li>
      </ul>
    </li>
  </ul>

</div>

我已将宽度更改为自动
.navigation > ul > li:hover .sub-menu {
宽度:自动；
}

.navigation {
  width: 100%;
  float: left;
  background: #008271;
  min-height: 50px;
  font-family: segoe ui;
  padding: 0 30px;
}
.navigation,
.navigation * {
  box-sizing: border-box;
}
.navigation ul {
  padding: 0;
  margin: 0;
  list-style: none;
}
.navigation .nav-right {
  float: right;
}
.navigation > ul > li {
  display: block;
  float: left;
  position: relative;
}
.navigation > ul > li > a {
  display: block;
  color: #fff;
  height: 50px;
  line-height: 50px;
  text-align: center;
  padding: 0 15px;
  font-size: 15px;
}
.navigation > ul > li.drop-menu:hover > a,
.navigation > ul > li.drop-menu > a:hover {
  background: #01675a;
}
.navigation .sub-menu {
  display: none
}
.navigation > ul > li:hover .sub-menu {
  width: auto;
  display: block;
  position: absolute;
  top: 50px;
  background: #fff;
  min-width: 160px;
  right: 0;
  border: 1px solid rgba(0, 0, 0, .15);
  box-shadow: 0 6px 12px rgba(0, 0, 0, .17);
  padding: 5px 0;
  -webkit-background-clip: padding-box;
  background-clip: padding-box;
}
.sub-menu > li > a {
  display: block;
  padding: 5px 15px;
  color: #333;
  white-space: nowrap;
  font-size: 14px;
}
.sub-menu > li > a:hover {
  background: #f5f5f5;
}
.caret {
  display: inline-block;
  width: 0;
  height: 0;
  margin-left: 2px;
  vertical-align: middle;
  border-top: 4px dashed;
  border-top: 4px solid\9;
  border-right: 4px solid transparent;
  border-left: 4px solid transparent;
}
.nav-left > li > a {
  font-size: 24px!important;
  font-weight: 300;
}

<div class="navigation">
  <ul class="nav-right">
    <li class="drop-menu">
      <a href="#">Teams <span class="caret"></span></a>
      <ul class="sub-menu">
        <li><a href="#">Team 1</a>
        </li>
      </ul>
    </li>
    <li class="drop-menu">
      <a href="#">Communities <span class="caret"></span></a>
      <ul class="sub-menu">
        <li><a href="#">Communities 1</a>
        </li>
        <li><a href="#">Communities 2 and much more content</a>
        </li>
      </ul>
    </li>
  </ul>

</div>
