Hello

i take the sample from your site to have a modale frame , but i have only a simple modal. does i need additional  library ?

<div class="modal fade bottom" id="frameModalBottom" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">

<!-- Add class .modal-frame and then add class .modal-bottom (or other classes from list above) to set a position to the modal -->
<div class="modal-dialog " role="document">


<div class="modal-content">
<div class="modal-body">
<div class="row d-flex justify-content-center align-items-center">

<p class="pt-3 pr-2">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Impedit nisi quo provident fugiat reprehenderit nostrum
quos..
</p>

<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
</div>

i open with javascript like this :

$("#frameModalBottom").modal("show");

but i get a simple modale , with black background and i don(t want it.
