Question

我想知道如何重新定位下拉菜单。

我想要实现的是虚假搜索。因此，当您单击搜索按钮时，它会激活带有假结果的下拉列表。我试图重新定位下拉菜单，使其看起来像是来自搜索。

这是我的代码 https://jsfiddle.net/judison/45f50ws9/

.searchBar {
  background-color: #67B4AD;
  color: white;
  width: 280px;
  border: none;
}
.dropdown-menu {
  right: 100px;
}
.add-on .dropdown > .btn {
  border: none;
  -webkit-box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
  box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
  color: white;
  background-color: #67B4AD;
}
/* stop the glowing blue shadow */

.add-on .form-control:focus {
  color: white;
  box-shadow: none;
  -webkit-box-shadow: none;
  background-color: #67B4AD;
}

<form class="navbar-form navbar-left" role="search">
  <div class="searchBarPadding form-group">
    <div class="input-group add-on">
      <input style="height:22px;" type="text" class="searchBar" placeholder=" &nbsp; Search">
      <div class="input-group-btn">
        <div class="dropdown">
          <button style="height:22px;" class="btn btn-default dropdown-toggle" type="button" data-toggle="dropdown"><i class="glyphicon glyphicon-search" style="height:10px;"></i>
          </button>
          <ul class="dropdown-menu">
            <li><a href="#">HTML</a>
            </li>
            <li class="disabled"><a href="#">CSS</a>
            </li>
            <li><a href="#">JavaScript</a>
            </li>
            <li class="divider"></li>
            <li><a href="#">About Us</a>
            </li>
          </ul>
        </div>
      </div>

    </div>
</form>

我真的很感激你的建议！

Answer 1

这是一个非常基本的例子，你可以建立

Codepen http://codepen.io/noobskie/pen/xwEXpv

刚刚向.dropdown-toggle添加了一个点击事件，该事件将在下拉列表中淡出并删除相对位置

.input-group-btn,
.dropdown{
  position:initial;
}

Answer 2

这可能是你想要完成的。您可以附加添加的按钮，并将dropdown-menu的宽度调整为form-control类，以使它们的总宽度相同。

#searchForm .form-control {
  background-color: #67B4AD;
  color: white;
  width: 280px;
  border: none;
}
#searchForm .dropdown-menu {
  width: 320px;
}
#searchForm .btn.btn-default {
  border: 1px solid #67B4AD;
  -webkit-box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
  box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
  color: white;
  background-color: #67B4AD;
}
/* stop the glowing blue shadow */

#searchForm .form-control:focus {
  color: white;
  box-shadow: none;
  -webkit-box-shadow: none;
  background-color: #67B4AD;
}
@media (max-width: 767px) {
  #searchForm .form-control {
    width: 100%;
  }
  #searchForm .dropdown-menu {
    width: auto;
  }
}
