Adjust the alignment of the dropdownlist in a navbar Bootstrap

I do not know if I'm doing this correctly, but I need to create a dropdownlist in my navbar to show a list of branches that will come from the database. The problem is that when I insert it, it is misaligned vertically. I believe it is because of some class that needs to be informed correctly. Does anyone know how to help me?

<li><divclass="form-group">
                            <label class="col-md-2 control-label">Filial Administrada</label>
                            <div class="col-md-3">
                                <select data-plugin="selectpicker" title="Selecione uma opção" class="show-tick show-menu-arrow">
                                    <option>FILIAL 1</option>
                                    <option>FILIAL 2</option>
                                    <option>FILIAL 3</option>
                                    <option>FILIAL 4</option>
                                </select>
