    <div class="modal-dialog" role="document">
        <div class="modal-content">
            <form>
                <div class="modal-header">
                    <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
                    <h4 class="modal-title" id="exampleModalLabel">New message</h4>
                </div>
                <div class="modal-body">
                    <div class="form-group">
