我正在尝试创建一个搜索框,如下所示:文本框和下拉列表显示为单个元素,并由一条小的垂直线分隔。如下图所示。我专注于实现“名称”和“位置”之间的垂直线


我试图通过html中的CSS实现此功能。我试图将“名称”文本框的右边框显示调整为可见,并删除所有其他边框。

      <input type="text" class="form-control" style="border:none; border-right: 1px solid black; border-radius:50px;">
      <div class="dropdown">
  <button class="btn btn-primary dropdown-toggle" type="button" data-toggle="dropdown" style="background-color: white; color:black; border:none">Dropdown Example
  <span class="caret"></span></button>
  <ul class="dropdown-menu" style="background-color: white;">
    <li><a href="#">HTML</a></li>

    <li><a href="#">JavaScript</a></li>
  </ul>
</div></div>

但这是行不通的。由于我的文本框需要圆角,因此对我来说似乎很难实现。还有其他技巧可以解决吗?如何使视图符合预期?请帮忙。提前致谢。

最佳答案

检查更新的更改

border-radius:50px 0px 0px 50px;




线使用

.dropdown:before{
  position:absolute;
  content:'';
  left:0px;
  height:28px;
  width:2px;
  background:#000000;
  top:3px;
}




.dropdown .btn{
  height:34px;
}

.form-group input:focus,.form-group .dropdown:focus,.form-group button:focus{
  outline:0px;
  box-shadow: none;
}



.dropdown:before{
  position:absolute;
  content:'';
  left:0px;
  height:28px;
  width:2px;
  background:#000000;
  top:3px;
}
