Bootstrap 5 floating labels

I was interesting in incorporating the floating labels from Bootstrap 5:
https://getbootstrap.com/docs/5.0/forms/floating-labels/

But it requires an unconventional order for the input and the label (input first) and also a "for" attribute for the label.

<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>

Offhand I don't see a way to implement this with Editor, even when making a plugin, because there's no a way to control the order of the label or add an attribute to it.

Am I mistaken or looking in the wrong place?
