Support CoreUI Development

CoreUI is an MIT-licensed open source project and is completely free to use. However, the amount of effort needed to maintain and develop new features for the project is not sustainable without proper financial backing.

You can support our Open Source software development in the following ways:

  • Buy the CoreUI PRO, and get access to PRO components, and dedicated support.
  • Became a sponsor, and get your logo on BACKERS.md/README.md files or each site of this documentation
  • Give us a star ⭐️ on Github.

Floating labels

Create beautifully simple form labels that float over your input fields.

Example

Wrap a pair of <input class="form-control"> and <label> elements in .form-floating to enable floating labels with CoreUI for 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="[email protected]">
  <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="[email protected]" value="[email protected]">
  <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="[email protected]" value="[email protected]">
  <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>

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="[email protected]">
  <label for="floatingEmptyPlaintextInput">Empty input</label>
</div>
<div class="form-floating mb-3">
  <input type="email" readonly class="form-control-plaintext" id="floatingPlaintextInput" placeholder="[email protected]" value="[email protected]">
  <label for="floatingPlaintextInput">Input with value</label>
</div>

Layout

When working with the CoreUI for 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="[email protected]" value="[email protected]">
      <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>
</div>
