Bootstrap multiselect dropdown is not visible

提问by Neha

Despite the fact that I can make this bootstrap-multiselect work in independent file, I'm not able to see the dropdown list once I click on caret, even if I included it in portal files.

尽管我可以让这个 bootstrap-multiselect 在独立文件中工作,但一旦我点击插入符号,我就无法看到下拉列表,即使我将它包含在门户文件中。

I have already used bootstrap-datepicker, datetimepicker, chosen, and backbone.js

我已经用过 bootstrap-datepicker、datetimepicker、selected、backbone.js

This is the line which is supposed to do the trick

这是应该做的伎俩的线

$('.insightList').multiselect({
            selectAllText: true
});

Does anyone have an idea of what can be the cause for not adding class 'open' for 'btn-group'?

有没有人知道不为“btn-group”添加“open”类的原因是什么?

![On click also there is only btn-group class for div whether it should add open class][1] Thanks in advance

![点击也只有btn-group类用于div是否应该添加开放类][1]提前致谢

Make sure your HTML structure for the dropdown is as follows:

确保下拉菜单的 HTML 结构如下:
