Headless UI提供了一个下拉菜单的示例，当您单击按钮时，下拉菜单将在下面打开。

代码如下所示：

import { Menu, Transition } from '@headlessui/react'
import { Fragment, useEffect, useRef, useState } from 'react'
import { ChevronDownIcon } from '@heroicons/react/solid'

export default function Example() {
  return (
    <div className="w-56 text-right fixed top-16">
      <Menu as="div" className="relative inline-block text-left">
        <div>
          <Menu.Button className="inline-flex justify-center w-full px-4 py-2 text-sm font-medium text-white bg-black rounded-md bg-opacity-20 hover:bg-opacity-30 focus:outline-none focus-visible:ring-2 focus-visible:ring-white focus-visible:ring-opacity-75">
            Options
            <ChevronDownIcon
              className="w-5 h-5 ml-2 -mr-1 text-violet-200 hover:text-violet-100"
              aria-hidden="true"
            />
          </Menu.Button>
        </div>
        <Transition
          as={Fragment}
          enter="transition ease-out duration-100"
          enterFrom="transform opacity-0 scale-95"
          enterTo="transform opacity-100 scale-100"
          leave="transition ease-in duration-75"

我修改的是<Menu.Items className="-top-2 transform -translate-y-full absolute right-0 w-56 origin-top-right bg-white divide-y divide-gray-100 rounded-md shadow-lg ring-1 ring-black ring-opacity-5 focus:outline-none">

只需向Menu.Items添加“底部满”类...

<Menu.Items className="bottom-full" >
  ...
</Menu.Items>
