Afkrydsningsfelter

Afkrydsningsfelter bruges, hvis du ønsker, at brugeren skal vælge et hvilket som helst antal muligheder fra en liste over forudindstillede muligheder.

Eksempel

<div class="form-check">
  <input class="form-check-input" type="checkbox" id="check1" name="option1" value="something" checked>
  <label class="form-check-label">Option 1</label>
</div>

<div class="container mt-3">
  <h2>Checkboxes</h2>
  <p>To style a checkbox, use a container element with a .form-check class, and add .form-check-label to labels, and .form-check-input to the input with type="checkbox".</p>
  <p>The form below contains three checkboxes. The first option is checked by default, and the last option is disabled:</p>
  <form action="/action_page.php">
    <div class="form-check">
      <input type="checkbox" class="form-check-input" id="check1" name="option1" value="something" checked>
      <label class="form-check-label" for="check1">Option 1</label>
    </div>
    <div class="form-check">
      <input type="checkbox" class="form-check-input" id="check2" name="option2" value="something">
      <label class="form-check-label" for="check2">Option 2</label>
    </div>
    <div class="form-check">
      <input type="checkbox" class="form-check-input" disabled>
      <label class="form-check-label">Option 3</label>
    </div>
    <button type="submit" class="btn btn-primary mt-3">Submit</button>
  </form>
</div>

</body>
</html>

Eksempel forklaret

For at style afkrydsningsfelter skal du bruge et indpakningselement med class="form-check" for at sikre korrekte margener for etiketter og afkrydsningsfelter.

Tilføj derefter klassen .form-check-label til etiketelementer og .form-check-input at style afkrydsningsfelter korrekt inde i .form-check containeren.

Brug attributten checked, hvis du ønsker, at afkrydsningsfeltet skal være markeret som standard.

Radioknapper

Radioknapper bruges, hvis du vil begrænse brugeren til kun ét valg fra en liste over forudindstillede muligheder.

Eksempel

<div class="form-check">
  <input type="radio" class="form-check-input" id="radio1" name="optradio" value="option1" checked>Option 1
  <label class="form-check-label" for="radio1"></label>
</div>
<div class="form-check">
  <input type="radio" class="form-check-input" id="radio2" name="optradio" value="option2">Option 2
  <label class="form-check-label" for="radio2"></label>
</div>
<div class="form-check">
  <input type="radio" class="form-check-input" disabled>Option 3
  <label class="form-check-label"></label>
</div>

  <p>The form below contains three radio buttons. The first option is checked by default, and the last option is disabled:</p>
  <form action="/action_page.php">
    <div class="form-check">
      <input type="radio" class="form-check-input" id="radio1" name="optradio" value="option1" checked>

Vippekontakter

Hvis du ønsker, at dit afkrydsningsfelt skal udformes som en skiftekontakt, skal du bruge klassen .form-switch sammen med .form- check container:

Eksempel

<div class="form-check form-switch">
  <input class="form-check-input" type="checkbox" id="mySwitch" name="darkmode" value="yes" checked>
  <label class="form-check-label" for="mySwitch">Dark Mode</label>
</div>
