Flex行内Dropdown菜单无法悬浮，需按图示调整布局

我有一个Accordion组件，其头部包含采用flex布局的文本框，右侧配有图标。当前Dropdown菜单在flex行内无法正常悬浮，需要将菜单调整为下图所示的位置。

<html>

<head>
  <style>
    .accordion {
      margin: 30px;
    }
    
    .accordion-button.collapsed {
      border-bottom: #ccc 1px solid
    }
    
    .accordion-body {
      border-left: #673ab744 1px solid;
      border-bottom: #673ab744 1px solid;
      border-right: #673ab744 1px solid
    }
    
    .accordion-button {
      display: inline!important
    }
    
    .flx-row {
      display: flex;
      justify-content: space-between;
    }
  </style>

问题根源是给.accordion-button设置的display: inline!important破坏了Bootstrap下拉菜单的定位上下文，同时flex容器的布局限制了菜单的正常悬浮。调整方案如下：

1. 移除.accordion-button的display: inline!important，改用flex布局让按钮内部元素正常排列
2. 给下拉按钮的父容器添加相对定位，确保下拉菜单以正确元素为定位基准
3. 优化flex容器样式，让头部内容布局更合理

修改后的CSS代码：

.accordion {
  margin: 30px;
}

.accordion-button.collapsed {
  border-bottom: #ccc 1px solid
}

.accordion-body {
  border-left: #673ab744 1px solid;
  border-bottom: #673ab744 1px solid;
  border-right: #673ab744 1px solid
}

/* 移除inline设置，改用flex让按钮内部元素正常排列 */
.accordion-button {
  display: flex!important;
  flex-direction: column;
  align-items: flex-start;
  padding: 1rem 1.25rem;
}

.flx-row {
  display: flex;
  justify-content: space-between;
  width: 100%;
  align-items: center;
}

/* 给下拉按钮容器添加相对定位，作为下拉菜单的定位上下文 */
.btn-group {
  position: relative;
}

保持原有HTML结构不变，修改后下拉菜单会相对于右侧的“More”按钮悬浮，不再被flex行限制，达到目标效果。
