    <select class="form-select" id="sel1" name="sellist1">
      <option>1</option>
      <option>2</option>
      <option>3</option>
      <option>4</option>
    </select>
    <br>
    
    <label for="sel2" class="form-label">多选下拉菜单：</label>
    <select multiple class="form-select" id="sel2" name="sellist2">
      <option>1</option>
      <option>2</option>
