Bootstrap 4: Stop collapse from pushing content down
提问by Retros
I'm using Bootstrap 4 Collapse and it's working perfectly, I just want to have one thing changed, if possible. Is there a way to stop it from pushing down the content beneath it, but instead to go over it? Is that possible to achieve? And how?
我正在使用 Bootstrap 4 Collapse 并且它运行良好，如果可能的话，我只想改变一件事。有没有办法阻止它向下推它下面的内容，而是跳过它？这有可能实现吗？如何？
Here's the basic HTML for it:
这是它的基本 HTML：
<p>
<a class="btn btn-primary" data-toggle="collapse" href="#collapseExample" aria-expanded="false" aria-controls="collapseExample">
Link with href
</a>
</p>
<div class="collapse" id="collapseExample">
<div class="card card-block">
Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. Nihil anim keffiyeh helvetica, craft beer labore wes anderson cred nesciunt sapiente ea proident.
</div>
</div>
<div>Content goes here</div>

You can also use the .align-items-endclass to your menu container.
this class used flex property introduce in BS4.
您还可以在.align-items-end菜单容器中使用该类。这个类使用了 BS4 中引入的 flex 属性。
