重寫後的標題為：How can I use Tailwind CSS to create animated dropdown menu with adjustable height?
我正在使用：Tailwindcss、React 和 Next.js 進行業餘專案。
我正在嘗試建立一個響應式導覽欄，當螢幕尺寸達到順風定義的「sm」尺寸時，它會顯示一個漢堡選單。
當我點擊漢堡包圖示時，我希望菜單從高度 0 過渡到 max-h-40。
我覺得我在下面的程式碼中遺漏了一些微不足道的東西，希望其他人看到這個可以看到我遺漏了什麼？
navbar.tsx

"use client";
import Image from "next/image";
import Link from "next/link";
import {
useState
} from "react";
import logo from "../public/finallang_favicon.ico";
export default function Navbar() {
const [showMenu, setShowMenu] = useState(false);
const toggleMenu = () => {
setShowMenu(!showMenu);
};

我嘗試過的事情：
- 將
height: "height"作為transitionProperty新增到我的 tailwind.config.js - #將可能遺失的
overflow-hidden類別名稱加入我的選單類別中 - 在下拉式選單的類別中在
transition-all和transition-[height]之間切換
當前行為： 當前行為的動圖
我期望發生什麼：
- 下拉選單應在 500 毫秒的持續時間內從高度 0 過渡到最大高度 10rems (max-h-40)，並使用緩入過渡計時功能。
