【问题描述】：

我正在制作一个 react + tailwind 应用程序，我需要一一实现两行导航栏。

对于我尝试过的代码，

     <nav className="relative flex flex-wrap items-center justify-between px-2 py-3 bg-pink-500 mb-3">
        <div className="container px-4 mx-auto flex flex-wrap items-center justify-between">
          <div className="w-full relative flex justify-between lg:w-auto lg:static lg:block lg:justify-start">
            <a
              className="text-sm font-bold leading-relaxed inline-block mr-4 py-2 whitespace-nowrap uppercase text-white"
              href="#pablo"
            >
              Logo 1
            </a>
            <button

我是 *** 的初学者，所以我不知道为什么上面的 sn-p 不适用各自的样式，但请在此处查看完整的工作示例，

https://codesandbox.io/s/tailwind-css-and-react-forked-909d1

在上面的示例中，您可以看到第一行菜单和第二行菜单都在同一行，但我需要将第二行菜单移到第一行下方。

请帮我实现这样的结果，

桌面视图：

| Logo 1   ------  Row-1-Menu-1 ---- Row-1-Menu-2 ---- Row-1-Menu-3 ----   Logo 2 |
|          ------  Row-2-Menu-1 ---- Row-2-Menu-2 ---- Row-2-Menu-3 ----          |

移动/标签视图

| Logo 1   --------- Logo 2 --- Hamburger Icon -- |

【问题讨论】：

您好，欢迎来到 ***。社区将很乐意为您提供帮助，但请遵循如何询问，尤其是如何提供“最小”可重现示例的指南：***.com/help/minimal-reproducible-example 此外，<Link ... /> 显然在代码示例中不起作用，因此您可以包含链接像你一样进行演示，甚至（更好）：在这里编写所有必要的（但最少的）css。我的猜测是，当你开始做这个最小的例子时，你会自己找到解决方案。

【参考方案1】：

您需要添加flexDirection: column 以在一列中呈现您的ul，并且需要从ul 中删除marginLeft: auto

试试下面的方法：-

import React from "react";

export default function Navbar( fixed ) 
  const [navbarOpen, setNavbarOpen] = React.useState(false);
  return (
    <>

          <div className="w-full relative flex justify-between lg:w-auto lg:static lg:block lg:justify-start">
            <a
              className="text-sm font-bold leading-relaxed inline-block mr-4 py-2 whitespace-nowrap uppercase text-white"
              href="#pablo"
            >
              Logo 1
            </a>
            <button
              className="text-white cursor-pointer text-xl leading-none px-3 py-1 border border-solid border-transparent rounded bg-transparent block lg:hidden outline-none focus:outline-none"
              type="button"
              onClick=() => setNavbarOpen(!navbarOpen)
            >
              <i className="fas fa-bars"></i>
