Multiselect in dropdown format in Bootstrap 4

Question

I’m having trouble finding a multiselect in bootstrap 4 with "dropdown" format. The only element it allows is this way:

I’d like to leave it in this format:

As I recall, this did not happen in the previous version of bootstrap.

Code used:

<link href="styles\bootstrap-4.1.1\bootstrap-4.1.1\dist\css\bootstrap.min.css" rel="stylesheet">

<select multiple class="form-control" data-actions-box="true">
           <option>Mustard</option>
           <option>Ketchup</option>
           <option>Relish</option>
</select> 

Someone can help me?

Answer 1

Try:

<select class="selectpicker" multiple>
  <option>Mustard</option>
  <option>Ketchup</option>
  <option>Relish</option>
</select>
