1.包含jQuery脚本、jQueryUI脚本、jQueryUI样式(必须保持包含脚本的顺序)。
1.将日期选择器的选择器更改为$(#date_filter_startmonthly input),因为日期选择器应始终指向输入字段。
1.更改日期选择器 prop ,以便允许选择月份或年份。

$(document).ready(main);
function main(){
  $('#date_filter_startmonthly input').datepicker({
          todayHighlight: true,
          format: 'yyyy-mm-dd',
          orientation: 'bottom auto',
          autoclose: true,
  });
}

<div class="form-group mb-2">
  <label class="col-form-lable mb-0">Start Date:</label>
  <div id="date_filter_startmonthly" class="input-group date" data-target-input="nearest">
    <div data-target="#date_filter_startmonthly" data-toggle="datepicker"class="input-group datetimepicker">
      <input type="text" class="form-control form-control-sm date-input" name="cb_sdate" placeholder="YYYY-MM-DD">
      <div class="input-group-addon "></div>
    </div>
  </div>
</div>
