A simple, lightweight jQuery plugin for creating Material Design style inputs that transform the Bootstrap 4 form label into floating labels when the text fields are focused or clicked.

How to use it:

1. Insert the JavaScript materialize-inputs.jquery.js and Stylesheet input-material.css into your Bootstrap 4 project.

<!-- Bootstrap 4 -->
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" integrity="sha384-MCw98/SFnGE8fJT3GXwEOngsV7Zt27NXFoaoApmYm81iuXoPkFOJwJ8ERdknLPMO" crossorigin="anonymous">
<script src="https://code.jquery.com/jquery-3.3.1.min.js" integrity="sha256-FgpCb/KJQlLNfOu91ta32o/NMZxltwRo8QtmkMRdAu8=" crossorigin="anonymous"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.3/umd/popper.min.js" integrity="sha384-ZMP7rVo3mIykV+2+9J3UJ46jBk0WLaUAdn689aCwoqbBJiSnjAK/l8WvCWPIPm49" crossorigin="anonymous"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/js/bootstrap.min.js" integrity="sha384-ChfqqxuZUCnJSK3+MXmPNIyE6ZbWh2IMqE241rYiqJxyMiZ6OW/JmZQ5stwEULTy" crossorigin="anonymous"></script>

<!-- Material-style Inputs -->
<link rel="stylesheet" href="input-material.css">
<script src="materialize-inputs.jquery.js"></script>

2. Add the CSS class input-material to the form groups.

<form id="contact-form">
  <div class="form-group input-material">
      <input type="text" class="form-control" id="name-field" required>
      <label for="name-field">Name</label>
  </div>
  <div class="form-group input-material">
      <input type="email" class="form-control" id="email-field" required>
      <label for="email-field">Email</label>
  </div>
  <div class="form-group input-material">
      <textarea class="form-control" id="textarea-field" rows="3" required></textarea>
      <label for="textarea-field">Your Message</label>
  </div>
  <div class="text-center">
      <button type="submit" class="btn btn-primary">Send</button>
  </div>
</form>

3. Call the function materializeInputs to enable the floating labels on all the text fields within the document.

$('document').ready(function(){

  // enable material-style inputs in entire body
  $('body').materializeInputs();

});

4. You can also specify the target text fields using the selectors parameter.

$('document').ready(function(){

  $('form').materializeInputs(".input-material input-1, .input-material input-2");

});
