我一直在尝试在我的页面上显示下拉菜单，但它不起作用......
我的网页代码：
<div class="dropdown d-inline">
<div class="widget-header mr-3">
<button href="#" class="icon icon-sm rounded-circle border" data-toggle="dropdown"><i class="fa fa-shopping-cart"></i></button>
<span class="badge badge-pill badge-danger notify">{{ Cart::count() }}</span>
</div>
<div class="dropdown-menu p-3 dropdown-menu-right" style="min-width:280px;">
<figure class="itemside mb-3">
<div class="aside">
<img src="bootstrap-ecommerce-html/images/items/1.jpg" class="img-sm border">
</div>
<figcaption class="info align-self-center">
<p class="title">Name of item nice iteme</p>
<a href="#" class="float-right"><i class="fa fa-trash"></i></a>
<div class="price">$250</div> <!-- price-wrap.// -->
</figcaption>
</figure>
<figure class="itemside mb-3">
<div class="aside">
<img src="bootstrap-ecommerce-html/images/items/2.jpg" class="img-sm border">
</div>
<figcaption class="info align-self-center">
<p class="title">Some other item name is here</p>
<a href="#" class="float-right"><i class="fa fa-trash"></i></a>
<div class="price">$250</div> <!-- price-wrap.// -->
</figcaption>
</figure>
<figure class="itemside mb-3">
<div class="aside">
<img src="bootstrap-ecommerce-html/images/items/3.jpg" class="img-sm border">
</div>
<figcaption class="info align-self-center">
<p class="title">Another name of item item</p>
<a href="#" class="float-right"><i class="fa fa-trash"></i></a>
<div class="price">$250</div> <!-- price-wrap.// -->
</figcaption>
</figure>
<div class="price-wrap text-center py-3 border-top">
Subtotal: <strong class="h5 price">$1200</strong>
</div>
<a href="" class="btn btn-primary btn-block"> Checkout </a>
</div> <!-- drowpdown-menu.// -->
</div>

这是一个在Laravel上运行的.blade.php页面。 提前感谢您的帮助，我真的很卡住。
因此，似乎在.dropdown .d-inline后将<button>包装在div内会导致您的问题。这也是一个有效的CodePen(请注意，我为每个Bootstrap添加了一些属性到某些元素(。
