Navigační lišty

Navigační lišta je navigační záhlaví, které je umístěno v horní části stránky:

Základní navigační lišta

Pomocí Bootstrapu se může navigační panel roztáhnout nebo sbalit v závislosti na velikosti obrazovky.

Vytvoří se standardní navigační panel s třídou .navbar, za kterou následuje responzivní sbalovací třída: .navbar-expand-xxl| xl|lg|md|sm (skládá navigační panel svisle na xxvelké, extra velké, velké, střední nebo malé obrazovky).

Chcete-li přidat odkazy do navigační lišty, použijte buď prvek <ul> (nebo <div>) s class="navbar-nav". Poté přidejte prvky <li> s třídou .nav-item následovanou <a> prvek s třídou .nav-link:

Příklad

<!-- A grey horizontal navbar that becomes vertical on small screens -->
<nav class="navbar navbar-expand-sm bg-light">
  <div class="container-fluid">
    <!-- Links -->
    <ul class="navbar-nav">
      <li class="nav-item">
        <a class="nav-link" href="#">Link 1</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Link 2</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Link 3</a>
      </li>
    </ul>
  </div>
</nav>

  <h3>Basic Navbar Example</h3>
  <p>A navigation bar is a navigation header that is placed at the top of the page.</p>
  <p>The navbar-expand-xxl|xl|lg|md|sm class determines when the navbar should stack vertically (on xxlarge, extra large, large, medium or small screens).</p>
</div>

Vertikální navigační lišta

Odeberte třídu .navbar-expand-* a vytvořte navigační panel, který bude vždy svislý:

Příklad

<!-- A grey vertical navbar -->
<nav class="navbar bg-light">

Středová navigační lišta

Příklad

<nav class="navbar navbar-expand-sm bg-light justify-content-center">

<div class="container-fluid mt-3">
  <h3>Centered Navbar</h3>
  <p>Use the .justify-content-center class to center the navigation bar.</p>
  <p>In this example, the navbar will be centered on medium, large and extra large screens. On small screens it will be displayed vertically and left-aligned (because of the .navbar-expand-sm class).</p>
</div>

</body>

Barevný navigační panel




Ke změně barvy pozadí navigační lišty použijte kteroukoli z tříd .bg-color

.bg-primary
.bg-success
.bg-info
.bg-warnig
.bg-danger
.bg-secondary
.bg-dark 
.bg-light

Tip: Přidejte bílou barvu textu ke všem odkazům v navigační liště s třídou .navbar-dark nebo pomocí třídy .navbar-light přidejte černou barvu textu.

Příklad

<!-- Grey with black text -->
<nav class="navbar navbar-expand-sm bg-light navbar-light">
  <div class="container-fluid">
    <ul class="navbar-nav">
      <li class="nav-item">
        <a class="nav-link active" href="#">Active</a>
      </li>
     <li class="nav-item">
        <a class="nav-link" href="#">Link</a>

      <li class="nav-item">
        <a class="nav-link disabled" href="#">Disabled</a>

Aktivní/deaktivovaný stav: Přidejte třídu .active do <a> prvek pro zvýraznění aktuálního odkazu nebo třída .disabled pro označení, že na odkaz nelze kliknout.

Značka/Logo

Třída .navbar-brand se používá ke zvýraznění názvu značky/loga/projektu vaší stránky:

Příklad

<nav class="navbar navbar-expand-sm bg-dark navbar-dark">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">Logo</a>
  </div>
</nav>

Při použití třídy .navbar-brand s obrázky, Bootstrap 5 automaticky upraví styl obrázku tak, aby se vešel svisle na navigační panel.

Příklad

<nav class="navbar navbar-expand-sm bg-dark navbar-dark">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">
      <img src="logo.png" alt="Avatar Logo" style="width:40px;" class="rounded-pill">

</body>
</html>

Text navigační lišty

Použijte třídu .navbar-text k vertikálnímu zarovnání všech prvků uvnitř navbaru, které nejsou odkazy (zajišťuje správné odsazení a barvu textu).

Příklad

<nav class="navbar navbar-expand-sm bg-dark navbar-dark">
  <div class="container-fluid">
    <span class="navbar-text">Navbar text</span>
  </div>
</nav>

<div class="container-fluid mt-3">
  <h3>Navbar Text</h3>
  <p>Use the .navbar-text class to vertical align any elements inside the navbar that are not links (ensures proper padding).</p>
</div>

</body>
</html>

Velmi často, zejména na malých obrazovkách, chcete skrýt navigační odkazy a nahradit je tlačítkem, které by je mělo po kliknutí odhalit.

Chcete-li vytvořit skládací navigační panel, použijte tlačítko s class="navbar-toggler", data-bs-toggle="collapse" a data-bs-target="# thetarget". Poté zabalte obsah navigační lišty (odkazy atd.) do prvku <div> pomocí class="collapse navbar-collapse", za kterým následuje ID odpovídající data-bs-target tlačítka: "thetarget".

Příklad

<nav class="navbar navbar-expand-sm bg-dark navbar-dark">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">Logo</a>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#collapsibleNavbar">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="collapsibleNavbar">

  <p>Tip: You can also remove the .navbar-expand-md class to ALWAYS hide navbar links and display the toggler button.</p>

Tip: Můžete také odebrat třídu .navbar-expand-md a VŽDY tak skrýt odkazy na navigační liště a zobrazit přepínací tlačítko.

Navbar s rozevíracím seznamem

Navigační panely mohou také obsahovat rozevírací nabídky:

Příklad

<li class="nav-item dropdown">
  <a class="nav-link dropdown-toggle" href="#" role="button" data-bs-toggle="dropdown">Dropdown</a>
  <ul class="dropdown-menu">
    <li><a class="dropdown-item" href="#">Link</a></li>
    <li><a class="dropdown-item" href="#">Another link</a></li>
    <li><a class="dropdown-item" href="#">A third link</a></li>

Formuláře a tlačítka navigační lišty

Formuláře můžete také zahrnout do navigační lišty:

Příklad

<nav class="navbar navbar-expand-sm navbar-dark bg-dark">
  <div class="container-fluid">
    <a class="navbar-brand" href="javascript:void(0)">Logo</a>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#mynavbar">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="mynavbar">
      <ul class="navbar-nav me-auto">
        <li class="nav-item">
          <a class="nav-link" href="javascript:void(0)">Link</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="javascript:void(0)">Link</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="javascript:void(0)">Link</a>
        </li>
      </ul>
      <form class="d-flex">
        <input class="form-control me-2" type="text" placeholder="Search">
        <button class="btn btn-primary" type="button">Search</button>
      </form>
    </div>
  </div>
</nav>

Pevná navigační lišta

Navigační lišta může být také upevněna v horní nebo dolní části stránky.

Pevná navigační lišta zůstává viditelná na pevné pozici (nahoře nebo dole) nezávisle na posouvání stránky.

Třída .fixed-top zafixuje navigační lištu na nahoře:

Příklad

<nav class="navbar navbar-expand-sm bg-dark navbar-dark fixed-top">
   …
</nav>

Použijte třídu .fixed-bottom, aby navigační lišta zůstala na spodní část stránky:

Použijte třídu .sticky-top k tomu, aby byla navigační lišta pevná/zůstala v horní části stránky, když se posunete mimo silný> to. Poznámka: Tato třída nefunguje v IE11 a dřívějších verzích (bude s ní nakládáno jako s position:relative).
