我尝试在bootstrap 4中使用顶级导航和侧边栏但是它并不顺利
我有header.jsp用作顶级导航。 它使用操作标记与侧边栏页面链接。像这样
<header>
<jsp:include page="../subPage/header.jsp"/>
</header>
<body>
<div class="sidebar"> ... </div>
</body>
但它不起作用。 It fell apart
之后，我搜索了网页并调整了侧栏的css
.sidebar { position: fixed; }
但它也不起作用because of overlapping
我可以使用哪些提示？
$(document).ready(function () {
$("#wrapper").toggleClass("toggled");
