Example

Email address

Example textarea

html

<div class="mb-3">
  <label for="exampleFormControlInput1" class="form-label">Email address</label>
  <input type="email" class="form-control" id="exampleFormControlInput1" placeholder="[email protected]">
</div>
<div class="mb-3">
  <label for="exampleFormControlTextarea1" class="form-label">Example textarea</label>
  <textarea class="form-control" id="exampleFormControlTextarea1" rows="3"></textarea>
</div>

Sizing

Set heights using classes like .form-control-lg and .form-control-sm.

html

<input class="form-control form-control-lg" type="text" placeholder=".form-control-lg" aria-label=".form-control-lg example">
<input class="form-control" type="text" placeholder="Default input" aria-label="default input example">
<input class="form-control form-control-sm" type="text" placeholder=".form-control-sm" aria-label=".form-control-sm example">

Disabled

Add the disabled boolean attribute on an input to give it a grayed out appearance, remove pointer events, and prevent focusing.

html

<input class="form-control" type="text" placeholder="Disabled input" aria-label="Disabled input example" disabled>
<input class="form-control" type="text" value="Disabled readonly input" aria-label="Disabled input example" disabled readonly>

Readonly

Add the readonly boolean attribute on an input to prevent modification of the input’s value. readonly inputs can still be focused and selected, while disabled inputs cannot.

html

<input class="form-control" type="text" value="Readonly input here..." aria-label="readonly input example" readonly>

Readonly plain text

If you want to have <input readonly> elements in your form styled as plain text, replace .form-control with .form-control-plaintext to remove the default form field styling and preserve the correct margin and padding.

Password

html

  <div class="mb-3 row">
    <label for="staticEmail" class="col-sm-2 col-form-label">Email</label>
    <div class="col-sm-10">
      <input type="text" readonly class="form-control-plaintext" id="staticEmail" value="[email protected]">
    </div>
  </div>
  <div class="mb-3 row">
    <label for="inputPassword" class="col-sm-2 col-form-label">Password</label>
    <div class="col-sm-10">
      <input type="password" class="form-control" id="inputPassword">
    </div>
  </div>

html

<form class="row g-3">
  <div class="col-auto">
    <label for="staticEmail2" class="visually-hidden">Email</label>
    <input type="text" readonly class="form-control-plaintext" id="staticEmail2" value="[email protected]">
  </div>
  <div class="col-auto">
    <label for="inputPassword2" class="visually-hidden">Password</label>
    <input type="password" class="form-control" id="inputPassword2" placeholder="Password">
  </div>
  <div class="col-auto">
    <button type="submit" class="btn btn-primary mb-3">Confirm identity</button>
  </div>
</form>

Default file input example

Multiple files input example

Disabled file input example

Small file input example

Large file input example

html

<div class="mb-3">
  <label for="formFile" class="form-label">Default file input example</label>
  <input class="form-control" type="file" id="formFile">
</div>
<div class="mb-3">
  <label for="formFileMultiple" class="form-label">Multiple files input example</label>
  <input class="form-control" type="file" id="formFileMultiple" multiple>
</div>
<div class="mb-3">
  <label for="formFileDisabled" class="form-label">Disabled file input example</label>
  <input class="form-control" type="file" id="formFileDisabled" disabled>
</div>
<div class="mb-3">
  <label for="formFileSm" class="form-label">Small file input example</label>
  <input class="form-control form-control-sm" id="formFileSm" type="file">
</div>
<div>
  <label for="formFileLg" class="form-label">Large file input example</label>
  <input class="form-control form-control-lg" id="formFileLg" type="file">
</div>

Color

Set the type="color" and add .form-control-color to the <input>. We use the modifier class to set fixed heights and override some inconsistencies between browsers.

Color picker

html

<label for="exampleColorInput" class="form-label">Color picker</label>
<input type="color" class="form-control form-control-color" id="exampleColorInput" value="#563d7c" title="Choose your color">

Datalists

Datalists allow you to create a group of <option>s that can be accessed (and autocompleted) from within an <input>. These are similar to <select> elements, but come with more menu styling limitations and differences. While most browsers and operating systems include some support for <datalist> elements, their styling is inconsistent at best.

Learn more about support for datalist elements.

Datalist example

html

<label for="exampleDataList" class="form-label">Datalist example</label>
<input class="form-control" list="datalistOptions" id="exampleDataList" placeholder="Type to search...">
<datalist id="datalistOptions">
  <option value="San Francisco">
  <option value="New York">
  <option value="Seattle">
  <option value="Los Angeles">
  <option value="Chicago">
</datalist>
