我有一个MCQ问题网站.在考试中,可能有来自不同科目的100-200个问题.所以我想让导航变得更容易.由于导航非常大,所以我想在开放主题下打开问题,即：当主题1处于活动状态时,只有主题1下的问题链接可见,如Bootstrap网站的右侧导航.我的工作样本如下.
I used Bootstrap scrollspy according to their site instruction and it
worked fine. But when I try to make it collapsible (like Bootstrap
website’s right navigation) it does not work.
我正在使用Bootstrap – 3.3.2
