指定下拉列表的值和标签
我使用data-filter-control="select">启动的下拉列表，其引导表扩展名为wenzhixin（github - filter control extension）。
我使用数据库中的数据填充下拉值，例如＆＃39; admin＆＃39;报告＆＃39;。我想更多地显示标签＆＃34;用户友好＆＃34;。这是一个HTML示例：<option value='report'>Report only</option>。
问题在于，如果我从我的数据库中提取报告并将其转换为仅报告，则它不会再过滤，因为它正在寻找对于后者在我的数据库而不是第一个。
下拉列表仅包含一个数据，这用于值AND标签，我得到HTML输出：<option value='report'>report</option>。
是否可以指定一个值，然后指定要显示的标签？
