I want all items in dropdown menus to be shown in RTL mode.

The actual behavior shows items in LTR mode.

The following code is for dropdown menu in the navbar:

<li mdbDropdown class="nav-item dropdown">
                        <a class="nav-link dropdown-toggle" href="#" id="navbarDropdownMenuLink" role="button"
                            mdbDropdownToggle aria-expanded="false">
                            گزینه
                        </a>
                        <ul mdbDropdownMenu class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">
                            <li>
                                <a class="dropdown-item" href="#">مورد 1</a>
                            </li>
                            <li>
                                <a class="dropdown-item" href="#">مورد 2</a>
                            </li>
                            <li>
                                <a class="dropdown-item" href="#">مورد 3</a>
                            </li>
                        </ul>
                    </li>
