[BUG] Select in modal form

[ceciud]

I try to use select type link "Tags input" from this page https://preview.tabler.io/form-elements.html to a modal with form (like https://preview.tabler.io/modals.html).
I put
<div class="mb-3"> <label class="form-label">Tags input</label> <select type="text" class="form-select" placeholder="Select tags" id="select-tags" value=""> <option value="HTML">HTML</option> <option value="JavaScript">JavaScript</option> <option value="CSS">CSS</option> <option value="jQuery">jQuery</option> <option value="Bootstrap">Bootstrap</option> <option value="Ruby">Ruby</option> <option value="Python">Python</option> </select> </div>
But remain not like select2, what i am wrong?

Thanks.
