HTML 代码

 <ol type="1" id="List">
  <div class="ollist">
    <div class="group-title"><span>group one title</span></div>
    <div class="items">
      <li class="item">
        <input type="checkbox" id="Check-1" value="1" class="checkbox-custom" name="item_name[]" />
        <label for="Check-1" class="checkbox-custom-label">List 1</label>
      </li>
    </div>
    <div class="items">
      <li class="item">
        <input type="checkbox" id="Check-2" value="2" class="checkbox-custom" name="item_name[]" />
        <label for="Check-2" class="checkbox-custom-label">List 2</label>
      </li>
    </div>
    <div class="items">
      <li class="item">
        <input type="checkbox" id="Check-3" value="3" class="checkbox-custom" name="item_name[]" />
        <label for="Check-3" class="checkbox-custom-label">List 3</label>
      </li>
    </div>
    <div class="items">
      <li class="item">
        <input type="checkbox" id="Check-4" value="4" class="checkbox-custom" name="item_name[]" />
        <label for="Check-4" class="checkbox-custom-label">List 4</label>
      </li>
    </div>
    <div class="items">
      <li class="item">
        <input type="checkbox" id="Check-5" value="5" class="checkbox-custom" name="item_name[]" />
        <label for="Check-5" class="checkbox-custom-label">List 5</label>
      </li>
    </div>
  </div>
</ol>

Jquery代码

jQuery(function($) {
  $('.ollistollist .group-title').each(function() {
    $(this).nextUntil('.group-title', '.items').data('group', this);
  });

  $('.ollist .items').has('input:checked').prependTo('.ollistollist');

  $('.ollist').on('change', 'input', function() {
    var $item = $(this).closest('.items');
    if (this.checked) {
      $item.insertBefore($('.ollist .group-title').first())
    } else {
      $item.appendTo($item.data('group'))
    }
  });
})
