问题描述
我正在尝试更改显示所选选项的selectpicker框的宽度，但无论我尝试什么，我都无法更改它，也无法更改框的颜色。
I am trying to change the width of the selectpicker box that shows selected options, but no matter what I try I am unable to change it, nor am I able to change the color of the box.
任何想法或建议都表示赞赏。
Any ideas or suggestions are appreciated.
我所假设的代码片段应更改框宽度如下（尽可能看我把它一直设置为25但宽度仍然很宽）：
Code Snippet for what I have assuming should change the box width is as follows (as you can see I set it all the way down to 25 but the width is still quite wide):
.selectpicker {
width: 25px;
您可以运行的代码段：
<script>
$(function() {
$('[data-toggle="tooltip"]').tooltip()
})
</script>
<script type = "text/javascript">
$(window).on('load', function() {
$('.selectpicker').selectpicker({
'selectedText': 'cat'
});
// $('.selectpicker').selectpicker('hide');
});
</script>

推荐答案
在select选项中使用data-content属性。
例如：
Use data-content attribute in select option. For example:
<select class="selectpicker form-control" data-live-search="true" id="subject_teacher_drop_down">
<option data-content="English">English</option>
<option data-content="Methodology of social...">Methodology of social science with special reference to economics</option>
</select>
