我试图在单击向下箭头时使整个#main-slider容器可展开。 a.next-down-chevron，我想要展示的唯一两件事是标题工程和向下箭头。我用谷歌搜索但只设法将三个容器隐藏在中间，所有的旋转木马箭头和标签仍在显示。我的代码：
<section id="main-slider" class="no-margin wow fadeInDown">
<a class="prev hidden-xs" href="#main-slider" data-slide="prev">
<i class="fa fa-chevron-left"></i>
</a>
<a class="next hidden-xs" href="#main-slider" data-slide="next">
<i class="fa fa-chevron-right"></i>
</a>
<div class="carousel slide" data-ride="carousel">
<ol class="carousel-indicators">
<li data-target="#main-slider" data-slide-to="0" class="active"></li>
<li data-target="#main-slider" data-slide-to="1"></li>
<li data-target="#main-slider" data-slide-to="2"></li>
</ol>

答案 0 :(得分：0)
如果你想将标题和开启者留在div的中间，你唯一的选择就是在div之外有一个副本Title和opener。并在点击时隐藏这些并显示主滑块，如下所示：
$('a.next-down-chevron').click(function(){
$('#engineering-trigger').hide();
$('#main-slider').show();
});
