title: Bootstrap 4.1 floating labels
body: <p>I've found on Google a doc example for Bootstrap 4.1 in which they feature floating labels: <a href="https://getbootstrap.com/docs/4.1/examples/floating-labels/" rel="nofollow noreferrer">getbootstrap.com/docs/4.1/examples/floating-labels/</a></p>
  
  <p>In that page, however, it is not explained how that can be achieved, and I can't find anything in the docs for v. 4.1. Floating labels are not even listed as a new feature in the <a href="https://github.com/twbs/bootstrap/issues/25375" rel="nofollow noreferrer">ship list</a>.</p>
  
  <p>Does anyone know if floating labels are supported?</p>
