Example
Wrap a pair of <input class="form-control"> and <label> elements in .form-floating to enable floating labels with Bootstrap’s textual form fields. A placeholder is required on each <input> as our method of CSS-only floating labels uses the :placeholder-shown pseudo-element. Also note that the <input> must come first so we can utilize a sibling selector (e.g., ~).
<div class="form-floating mb-3">
<input type="email" class="form-control" id="floatingInput" placeholder="name@example.com">
<label for="floatingInput">Email address</label>
</div>
<div class="form-floating">
<input type="password" class="form-control" id="floatingPassword" placeholder="Password">
<label for="floatingPassword">Password</label>
</div>When there’s a value already defined, <label>s will automatically adjust to their floated position.
<form class="form-floating">
<input type="email" class="form-control" id="floatingInputValue" placeholder="name@example.com" value="test@example.com">
<label for="floatingInputValue">Input with value</label>
</form>Form validation styles also work as expected.
<form class="form-floating">
<input type="email" class="form-control is-invalid" id="floatingInputInvalid" placeholder="name@example.com" value="test@example.com">
<label for="floatingInputInvalid">Invalid input</label>
</form>Textareas
By default, <textarea>s with .form-control will be the same height as <input>s.
<div class="form-floating">
<textarea class="form-control" placeholder="Leave a comment here" id="floatingTextarea"></textarea>
<label for="floatingTextarea">Comments</label>
</div>To set a custom height on your <textarea>, do not use the rows attribute. Instead, set an explicit height (either inline or via custom CSS).
<div class="form-floating">
<textarea class="form-control" placeholder="Leave a comment here" id="floatingTextarea2" style="height: 100px"></textarea>
<label for="floatingTextarea2">Comments</label>
</div>Selects
Other than .form-control, floating labels are only available on .form-selects. They work in the same way, but unlike <input>s, they’ll always show the <label> in its floated state. Selects with size and multiple are not supported.
<div class="form-floating">
<select class="form-select" id="floatingSelect" aria-label="Floating label select example">
<option selected>Open this select menu</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
<label for="floatingSelect">Works with selects</label>
</div>Disabled
Add the disabled boolean attribute on an input, a textarea or a select to give it a grayed out appearance, remove pointer events, and prevent focusing.
<div class="form-floating mb-3">
<input type="email" class="form-control" id="floatingInputDisabled" placeholder="name@example.com" disabled>
<label for="floatingInputDisabled">Email address</label>
</div>
<div class="form-floating mb-3">
<textarea class="form-control" placeholder="Leave a comment here" id="floatingTextareaDisabled" disabled></textarea>
<label for="floatingTextareaDisabled">Comments</label>
</div>
<div class="form-floating mb-3">
<textarea class="form-control" placeholder="Leave a comment here" id="floatingTextarea2Disabled" style="height: 100px" disabled>Disabled textarea with some text inside</textarea>
<label for="floatingTextarea2Disabled">Comments</label>
</div>
<div class="form-floating">
<select class="form-select" id="floatingSelectDisabled" aria-label="Floating label disabled select example" disabled>
<option selected>Open this select menu</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
<label for="floatingSelectDisabled">Works with selects</label>
</div>Readonly plaintext
Floating labels also support .form-control-plaintext, which can be helpful for toggling from an editable <input> to a plaintext value without affecting the page layout.
<div class="form-floating mb-3">
<input type="email" readonly class="form-control-plaintext" id="floatingEmptyPlaintextInput" placeholder="name@example.com">
<label for="floatingEmptyPlaintextInput">Empty input</label>
</div>
<div class="form-floating mb-3">
<input type="email" readonly class="form-control-plaintext" id="floatingPlaintextInput" placeholder="name@example.com" value="name@example.com">
<label for="floatingPlaintextInput">Input with value</label>
</div>Input groups
Floating labels also support .input-group.
<div class="input-group mb-3">
<span class="input-group-text">@</span>
<div class="form-floating">
<input type="text" class="form-control" id="floatingInputGroup1" placeholder="Username">
<label for="floatingInputGroup1">Username</label>
</div>
</div>When using .input-group and .form-floating along with form validation, the -feedback should be placed outside of the .form-floating, but inside of the .input-group. This means that the feedback will need to be shown using javascript.
<div class="input-group has-validation">
<span class="input-group-text">@</span>
<div class="form-floating is-invalid">
<input type="text" class="form-control is-invalid" id="floatingInputGroup2" placeholder="Username" required>
<label for="floatingInputGroup2">Username</label>
</div>
<div class="invalid-feedback">
Please choose a username.
</div>
</div>Layout
When working with the Bootstrap grid system, be sure to place form elements within column classes.
<div class="row g-2">
<div class="col-md">
<div class="form-floating">
<input type="email" class="form-control" id="floatingInputGrid" placeholder="name@example.com" value="mdo@example.com">
<label for="floatingInputGrid">Email address</label>
</div>
</div>
<div class="col-md">
<div class="form-floating">
<select class="form-select" id="floatingSelectGrid">
<option selected>Open this select menu</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
<label for="floatingSelectGrid">Works with selects</label>
</div>
</div>
