        <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
      </li>
    </ul>
  </div>
</nav>

Lan amarga kita nggunakake kelas kanggo navs kita, sampeyan bisa supaya pendekatan adhedhasar dhaftar tanggung yen seneng.

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <a class="navbar-brand" href="#">Navbar</a>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNavAltMarkup" aria-controls="navbarNavAltMarkup" aria-expanded="false" aria-label="Toggle navigation">

      <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a>
    </div>
  </div>
</nav>

Sampeyan uga bisa nggunakake dropdowns ing navbar nav. Menu gulung mudhun mbutuhake unsur bungkus kanggo posisi, dadi manawa sampeyan nggunakake unsur sing kapisah lan nested kanggo .nav-itemlan .nav-linkkaya ing ngisor iki.

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <a class="navbar-brand" href="#">Navbar</a>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNavDropdown" aria-controls="navbarNavDropdown" aria-expanded="false" aria-label="Toggle navigation">

          Dropdown link
        </a>
        <div class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">

        </div>
      </li>
    </ul>
  </div>
</nav>

Formulir

Selehake macem-macem kontrol wangun lan komponen ing navbar karo .form-inline.

<nav class="navbar navbar-light bg-light">
  <form class="form-inline">
    <input class="form-control mr-sm-2" type="search" placeholder="Search" aria-label="Search">
    <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
  </form>
</nav>

Elemen anak langsung .navbarnggunakake tata letak fleksibel lan bakal dadi standar justify-content: space-between. Gunakake utilitas fleksibel tambahan yen perlu kanggo nyetel prilaku iki.

<nav class="navbar navbar-light bg-light">
  <a class="navbar-brand">Navbar</a>
  <form class="form-inline">
    <input class="form-control mr-sm-2" type="search" placeholder="Search" aria-label="Search">
    <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
  </form>
</nav>

Grup input uga bisa digunakake:

<nav class="navbar navbar-light bg-light">
  <form class="form-inline">
    <div class="input-group">
      <div class="input-group-prepend">
        <span class="input-group-text" id="basic-addon1">@</span>
      </div>
      <input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="basic-addon1">
    </div>
  </form>
</nav>

Macem-macem tombol didhukung minangka bagéan saka formulir navbar iki uga. Iki uga minangka pangeling sing apik yen utilitas alignment vertikal bisa digunakake kanggo nyelarasake unsur ukuran sing beda.

<nav class="navbar navbar-light bg-light">
  <form class="form-inline">
    <button class="btn btn-outline-success" type="button">Main button</button>
    <button class="btn btn-sm btn-outline-secondary" type="button">Smaller button</button>
  </form>
</nav>

Teks

Navbar bisa ngemot potongan teks kanthi bantuan .navbar-text. Kelas iki nyetel alignment vertikal lan spasi horisontal kanggo strings teks.

<nav class="navbar navbar-light bg-light">
  <span class="navbar-text">
    Navbar text with an inline element
  </span>
</nav>

Nyampur lan cocog karo komponen lan keperluan liyane yen perlu.

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <a class="navbar-brand" href="#">Navbar w/ text</a>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarText" aria-controls="navbarText" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>
  <div class="collapse navbar-collapse" id="navbarText">
    <ul class="navbar-nav mr-auto">
      <li class="nav-item active">
        <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Features</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Pricing</a>
      </li>
    </ul>
    <span class="navbar-text">
      Navbar text with an inline element
    </span>
  </div>
</nav>

Skema warna

Theming navbar wis tau dadi luwih gampang thanks kanggo kombinasi kelas tema lan background-colorkeperluan. Pilih saka .navbar-lightkanggo nggunakake werna latar mburi cahya, utawa .navbar-darkkanggo werna latar mburi peteng. Banjur, setel karo .bg-*keperluan.

<nav class="navbar navbar-dark bg-dark">
  <!-- Navbar content -->
</nav>

<nav class="navbar navbar-dark bg-primary">
  <!-- Navbar content -->
</nav>

<nav class="navbar navbar-light" style="background-color: #e3f2fd;">
  <!-- Navbar content -->
</nav>

Wadhah

Senajan iku ora dibutuhake, sampeyan bisa mbungkus navbar ing .containertengah ing kaca utawa nambah siji ing mung tengah isi navbar ndhuwur tetep utawa statis .

<div class="container">
  <nav class="navbar navbar-expand-lg navbar-light bg-light">
    <a class="navbar-brand" href="#">Navbar</a>
  </nav>
</div>

Nalika wadhah kasebut ana ing navbar sampeyan, padding horisontal dicopot ing breakpoints sing luwih murah tinimbang .navbar-expand{-sm|-md|-lg|-xl}kelas sing ditemtokake. Iki mesthekake yen kita ora ngganda ing padding tanpa perlu ing viewports ngisor nalika navbar sampeyan ambruk.

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <div class="container">
    <a class="navbar-brand" href="#">Navbar</a>
  </div>
</nav>

Panggonan

Use our position utilities to place navbars in non-static positions. Choose from fixed to the top, fixed to the bottom, or stickied to the top (scrolls with the page until it reaches the top, then stays there). Fixed navbars use position: fixed, meaning they’re pulled from the normal flow of the DOM and may require custom CSS (e.g., padding-top on the <body>) to prevent overlap with other elements.

Also note that .sticky-top uses position: sticky, which isn’t fully supported in every browser.

<nav class="navbar navbar-light bg-light">
  <a class="navbar-brand" href="#">Default</a>
</nav>
<nav class="navbar fixed-top navbar-light bg-light">
  <a class="navbar-brand" href="#">Fixed top</a>
</nav>
<nav class="navbar fixed-bottom navbar-light bg-light">
  <a class="navbar-brand" href="#">Fixed bottom</a>
</nav>
<nav class="navbar sticky-top navbar-light bg-light">
  <a class="navbar-brand" href="#">Sticky top</a>
</nav>

Responsive behaviors

Navbars can utilize .navbar-toggler, .navbar-collapse, and .navbar-expand{-sm|-md|-lg|-xl} classes to change when their content collapses behind a button. In combination with other utilities, you can easily choose when to show or hide particular elements.

For navbars that never collapse, add the .navbar-expand class on the navbar. For navbars that always collapse, don’t add any .navbar-expand class.

Toggler

Navbar togglers are left-aligned by default, but should they follow a sibling element like a .navbar-brand, they’ll automatically be aligned to the far right. Reversing your markup will reverse the placement of the toggler. Below are examples of different toggle styles.

With no .navbar-brand shown in lowest breakpoint:

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarTogglerDemo01" aria-controls="navbarTogglerDemo01" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>
  <div class="collapse navbar-collapse" id="navbarTogglerDemo01">
