Select with search inside a modal

Due to a focus trap in modals, it is not possible to focus the outer elements (like select dropdown). You can use select data-mdb-container option to resolve this problem.

The data-mdb-container accepts selector of the element inside of wich select dropdown will be rendered. In this case, the selector should point to the modal container (the element with class .modal). It is important to use a unique selector to assign select to a specific modal.

      <!-- Button trigger modal -->
      <button type="button" class="btn btn-primary" data-mdb-toggle="modal" data-mdb-target="#exampleModal">
        Launch demo modal
