看到柳神的网站有这种菜单，但是没有写魔改教程，只好自己慢慢摸索了。

预计做好后是这种效果：

首先，修改\themes\butterfly\layout\includes\header\nav.pug:

nav#nav
  //- 左侧区域：包含指纹菜单和网站名
  span#blog-info
    #ls-menu-container
      i.fas.fa-fingerprint
      #ls-menu-panel
        .ls-section
          .ls-title 😀 个人网站
          .ls-grid
            a(href="/") #[i.fas.fa-rss] 个人博客
            a(href="https://github.com/bishshi") #[i.fab.fa-github] Github
        .ls-section
          .ls-title 😎 常用服务
          .ls-grid
            a(href="https://git.biss.click/biss") #[i.fas.fa-code] 代码仓库
            a(href="https://mm.biss.click") #[i.fas.fa-pen-nib] 日常yy
            a(href="https://statstic.biss.click") #[i.fas.fa-users] 访客统计
            a(href="https://pic.biss.click") #[i.fas.fa-image] 图床
            a(href="https://chat.biss.click") #[i.fas.fa-robot] AI网站
        .ls-section
          .ls-title 🛸 实用工具
          .ls-grid
            a(href="https://cover.biss.click") #[i.fas.fa-palette] 封面设计

    a.nav-site-title(href=url_for('/'))
      if theme.nav.logo
        img.site-icon(src=url_for(theme.nav.logo) alt='Logo')
      if theme.nav.display_title
        span.site-name=config.title

  //- 中间区域：关键！必须在 nav 下一级，以便 JS 切换类名
  if globalPageType === 'post' && theme.nav.display_post_title
    a.nav-page-title(href='javascript:void(0);' onclick='btf.scrollToDest(0, 500)')
      span.site-name=(page.title || config.title)

  //- 右侧区域
  #nav-right
    if theme.menu
      #menus
        != partial('includes/header/menu_item', {}, {cache: true})
    
    if theme.search.use || true
      #random-post-button
        a.site-page.social-icon#random-post-link(href='javascript:void(0);' onclick='randomPost()')
          i.fas.fa-solid.fa-shuffle
      #search-button
        a.site-page.social-icon.search-typesense-trigger
          i.fas.fa-search.fa-fw
      #toggle-menu
        span.site-page
          i.fas.fa-bars.fa-fw

在合适的目录下新建nav.css（例如\themes\butterfly\source\css\nav.css），这份css是磨砂玻璃的样式:

#nav-right{
  flex:1 1 auto;
  justify-content: flex-end;
  margin-left: auto;
  display: flex;
  flex-wrap:nowrap;
}
  
/* 导航栏居中 */

#sidebar #sidebar-menus .menus_items .menus_item {
    margin: 10px 0;
}
#sidebar #sidebar-menus .menus_items a.site-page {
    padding-left: 0;
}
#sidebar #sidebar-menus .menus_items .site-page {
    position: relative;
    display: block;
    padding: 6px 30px 6px 22px;
    color: var(--font-color);
    font-size: 1.15em;
    border: var(--style-border-always);
    background: var(--icat-card-bg);
    font-size: 14px;
    border-radius: 12px;
}
#sidebar #sidebar-menus .menus_items .site-page i:first-child {
    text-align: left;
    padding-left: 10px;
}

#nav #menus {
    display: flex;
    justify-content: center;
    width: 100%;
    position: absolute;
    left: 0;
    margin: 0;
    transform: translateZ(0);
}
#nav #blog-info {
    flex-wrap: nowrap;
    display: flex;
    align-items: center;
    z-index: 102;
    max-width: fit-content;
}
@media screen and (max-width: 900px) {
    #nav {
        padding: 0 15px;
    }
    #nav-group {
        padding: 0 0.2rem;
    }
    #rightside {
        right: -42px;
    }
}
/* IPAD菜单栏调整 */

/* 1. 容器溢出穿透 */
#nav, #blog-info, #nav-group {
  overflow: visible !important;
}

#ls-menu-container {
  position: relative !important;
  display: inline-flex !important;
  align-items: center;
  height: 100%;
  padding: 0 15px;
  cursor: pointer !important;
  z-index: 2000 !important;
}

/* 2. 悬浮面板：宽大且高不透明度 */
#ls-menu-panel {
  position: absolute !important;
  top: 100% !important;
  left: 0 !important;
  margin-top: 15px !important;
  width: 420px; 
  padding: 24px;

  /* 高不透明度磨砂玻璃 (0.9) */
  background: rgba(255, 255, 255, 0.95) !important;
  backdrop-filter: blur(20px) saturate(180%) !important;
  -webkit-backdrop-filter: blur(20px) saturate(180%) !important;

  transition: all 0.3s cubic-bezier(0.4, 0, 0.2, 1) !important;
  z-index: 999999 !important;
  cursor: default;
}

/* 3. 透明感应桥梁 */
#ls-menu-panel::before {
  content: "";
  position: absolute;
  top: -20px;
  left: 0;
  right: 0;
  height: 25px;
  background: transparent !important;
}

/* 4. 触发效果 */
#ls-menu-container:hover #ls-menu-panel {

  transform: translateY(0) !important;
}

#ls-menu-container:hover i.fa-fingerprint {
  color: #49b1f5;
  transform: scale(1.1);
}

/* 5. 内部网格：保持两列 */
.ls-section { margin-bottom: 22px; }
.ls-section:last-child { margin-bottom: 0; }
.ls-title { 
  color: #333; 
  font-weight: 800; 
  font-size: 15px; 
  margin-bottom: 12px; 
  opacity: 0.9;
}

.ls-grid { 
  display: grid !important; 
  grid-template-columns: repeat(2, 1fr); /* 恢复为两列 */
  gap: 10px; 
}

.ls-grid a { 
  color: #444 !important; 
  font-size: 14px !important; 
  padding: 10px 12px; 
  border-radius: 12px;
  display: flex;
  align-items: center;
  transition: all 0.2s ease;
  background: rgba(0, 0, 0, 0.02);
}

.ls-grid a:hover { 
  background: #49b1f5 !important; 
  color: #fff !important; 
  transform: translateX(4px); /* 悬停时轻微右移，增加动感 */
}

.ls-grid a i { 
  margin-right: 12px; 
  width: 20px; 
  text-align: center; 
  font-size: 15px;
}

/* 6. 深色模式适配 */
[data-theme='dark'] #ls-menu-panel {
  background: rgba(30, 30, 30, 0.95) !important;
  border-color: rgba(255, 255, 255, 0.1) !important;
}
[data-theme='dark'] .ls-title { color: #eee; }
[data-theme='dark'] .ls-grid a { 
  color: #ccc !important; 
  background: rgba(255, 255, 255, 0.05); 
}

#nav.show-title .nav-page-title {
  display: flex !important;
  opacity: 1 !important;
  visibility: visible !important;
  position: absolute !important;
  left: 50% !important;
  transform: translateX(-50%) !important;
  white-space: nowrap !important;
  z-index: 1000 !important;
}

#nav.show-title #menus,
#nav.show-title .nav-site-title {
  opacity: 0 !important;
  visibility: hidden !important;
  pointer-events: none !important;
}

#nav .nav-page-title {
  display: none; 
  transition: opacity 0.3s ease;
}

#nav #blog-info {
  overflow: visible !important;
}

然后在_config.butterfly.yml里面引用该css

- <link rel="stylesheet" href="/css/nav.css">

然后重新构建应该就可以看到效果了。
