Bootstrap 5: Sbalit

Obsah

Základní skládací

Sbalitelné jsou užitečné, když chcete skrýt a zobrazit velké množství obsahu:

Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.

Příklad

<button data-bs-toggle="collapse" data-bs-target="#demo">Collapsible</button>
<div id="demo" class="collapse">
Lorem ipsum dolor text....
</div>

Příklad vysvětlen

Třída .collapse označuje sbalitelný prvek (v našem příkladu <div>); toto je obsah, který se zobrazí nebo skryje kliknutím na tlačítko.

Chcete-li ovládat (zobrazit/skrýt) sbalitelný obsah, přidejte do prvku <a> nebo <button> atribut data-bs-toggle="collapse". Poté přidejte atribut data-bs-target="#id" a spojte tak tlačítko se sbalitelným obsahem (<div id="demo">).

Poznámka: Pro prvky <a> můžete místo atributu data- použít atribut href bs-target atribut:

Příklad

<a href="#demo" data-bs-toggle="collapse">Collapsible</a>
<div id="demo" class="collapse">
Lorem ipsum dolor text....
</div>

  </div>
</div>

</body>
</html>

Ve výchozím nastavení je sbalitelný obsah skrytý. Můžete však přidat třídu .show, která bude obsah zobrazovat ve výchozím nastavení:

Příklad

<div id="demo" class="collapse show">
Lorem ipsum dolor text....
</div>

Akordeon

Collapsible Group Item #1

Collapsible Group Item #2

Collapsible Group Item #3

Následující příklad ukazuje jednoduchý akordeon s prodloužením kartové komponenty.

Poznámka: Pomocí atributu data-bs-parent zajistíte, že všechny sbalitelné prvky pod zadaným nadřazeným prvkem budou uzavřeny, když jeden ze sbalitelných prvků položka je zobrazena.

Příklad

<div id="accordion">
  <div class="card">
    <div class="card-header">
      <a class="btn" data-bs-toggle="collapse" href="#collapseOne">
        Collapsible Group Item #1
      </a>
    </div>
    <div id="collapseOne" class="collapse show" data-bs-parent="#accordion">
      <div class="card-body">
        Lorem ipsum..
      </div>
    </div>
  </div>
  <div class="card">
    <div class="card-header">
      <a class="collapsed btn" data-bs-toggle="collapse" href="#collapseTwo">
        Collapsible Group Item #2
      </a>
    </div>
    <div id="collapseTwo" class="collapse" data-bs-parent="#accordion">
      <div class="card-body">
        Lorem ipsum..
      </div>
    </div>
  </div>
  <div class="card">
    <div class="card-header">
      <a class="collapsed btn" data-bs-toggle="collapse" href="#collapseThree">
        Collapsible Group Item #3
      </a>
    </div>
    <div id="collapseThree" class="collapse" data-bs-parent="#accordion">
      <div class="card-body">
        Lorem ipsum..
      </div>
    </div>
  </div>
