如何将分页下拉菜单移到显示jQuery Ajax DataTable数量旁边的底部

<div id="datatable-container">
    <div id="datatable-length" class="dataTables_length">
        <label>Show 
            <select name="datatable_length" aria-controls="datatable" class="custom-select custom-select-sm form-control form-control-sm">
                <option value="10">10</option>
                <option value="25">25</option>
                <option value="50">50</option>
                <option value="100">100</option>
            </select> entries
        </label>
    </div>
    <table id="datatable" class="display" style="width:100%"></table>
</div>

$(document).ready(function() {
    $('#datatable').DataTable({
        // 设置分页下拉菜单的位置
        dom: '<"row"<"col-sm-12 col-md-6"l><"col-sm-12 col-md-6"f>>' +
             '<"row"<"col-sm-12"tr>>' +
             '<"row"<"col-sm-12 col-md-5"i><"col-sm-12 col-md-7"p>>',
        // 其他DataTable选项...
    });
});
