Bootstrap 5: Formulários

Índice

Formulário empilhado

Todos os elementos textuais <input> e <textarea> com classe .form-control recebem o estilo de formulário adequado:

Email:

Password:

Remember me

Exemplo

<form action="/action_page.php">
  <div class="mb-3 mt-3">
    <label for="email" class="form-label">Email:</label>
    <input type="email" class="form-control" id="email" placeholder="Enter email" name="email">
  </div>
  <div class="mb-3">
    <label for="pwd" class="form-label">Password:</label>
    <input type="password" class="form-control" id="pwd" placeholder="Enter password" name="pswd">
  </div>
  <div class="form-check mb-3">
    <label class="form-check-label">
      <input class="form-check-input" type="checkbox" name="remember"> Remember me
    </label>
  </div>
  <button type="submit" class="btn btn-primary">Submit</button>
</form>

  <form action="/action_page.php">
    <div class="mb-3 mt-3">
      <label for="email">Email:</label>
      <input type="email" class="form-control" id="email" placeholder="Enter email" name="email">

    </div>

  </form>

Observe também que adicionamos uma classe .form-label a cada elemento do rótulo para garantir o preenchimento correto.

As caixas de seleção têm marcações diferentes. Eles são agrupados em torno de um elemento contêiner com .form-check e os rótulos têm uma classe de .form-check-label, enquanto caixas de seleção e botões de opção usam .form-check-input.

Área de texto

Comments:

Exemplo

<label for="comment">Comments:</label>
<textarea class="form-control" rows="5" id="comment" name="text"></textarea>

<div class="container mt-3">
  <h2>Textarea</h2>
  <p>Use the .form-control class to style textareas as well:</p>
  <form action="/action_page.php">
    <div class="mb-3 mt-3">
      <label for="comment">Comments:</label>
      &lt;textarea class="form-control" rows="5" id="comment" name="text">&lt;/textarea>
    </div>
    <button type="submit" class="btn btn-primary">Submit</button>
  </form>
</div>

</body>
</html>

Linha/grade do formulário (formulários embutidos)

Se você deseja que os elementos do seu formulário apareçam lado a lado, use .row e .col:

Exemplo

<form>
  <div class="row">
    <div class="col">
      <input type="text" class="form-control" placeholder="Enter email" name="email">
    </div>
    <div class="col">
      <input type="password" class="form-control" placeholder="Enter password" name="pswd">
    </div>
  </div>
</form>

  <h2>Inline Forms</h2>
  <p>If you want your form elements to appear side by side, use .row and .col:</p>
  <form>
    <div class="row">
      <div class="col">
        <input type="text" class="form-control" placeholder="Enter email" name="email">
      </div>
      <div class="col">
        <input type="password" class="form-control" placeholder="Enter password" name="pswd">
      </div>
    </div>
  </form>
</div>

</body>
</html>

Tamanho do controle de formulário

Você pode alterar o tamanho das entradas .form-control com .form-control-lg ou .form-control-sm:

Exemplo

<input type="text" class="form-control form-control-lg" placeholder="Large input">
<input type="text" class="form-control" placeholder="Normal input">
<input type="text" class="form-control form-control-sm" placeholder="Small input">

  <p>You can change the size of .form-control inputs with .form-control-lg or .form-control-sm:</p>
  <form>

    <input type="text" class="form-control form-control-sm mt-3" placeholder="Small input">
  </form>
</div>

Desativado e somente leitura

Use os atributos desativados e/ou somente leitura para desativar o campo de entrada:

Exemplo

<input type="text" class="form-control" placeholder="Normal input">
<input type="text" class="form-control" placeholder="Disabled input" disabled>
<input type="text" class="form-control" placeholder="Readonly input" readonly>

</head>
<body>

<div class="container mt-3">
  <h2>Disabled and Readonly</h2>
  <p>Use the disabled and/or readonly attributes to disable the input field:</p>
  <form>
    <input type="text" class="form-control" placeholder="Normal input">
    <input type="text" class="form-control mt-3" placeholder="Disabled input" disabled>
    <input type="text" class="form-control mt-3" placeholder="Readonly input" readonly>
  </form>
</div>

</body>
</html>

Entradas de texto simples

Use a classe .form-control-plaintext para estilizar um campo de entrada sem bordas, mas mantenha as margens e o preenchimento adequados:

Exemplo

<input type="text" class="form-control-plaintext" placeholder="Plaintext input">
<input type="text" class="form-control" placeholder="Normal input">

    <input type="text" class="form-control mt-3" placeholder="Normal input">
  </form>
</div>
