bootstrap4将滚动条添加到div

Question

我在div中使用stacked pills。问题是，有时div包含很多药片。我怎样才能为它添加一个滚动条？

<div class="row col-md-2"> 
<ul class="nav nav-pills nav-stacked"> 
    <li class="nav-item"> 
    <a class="nav-link active" href="#">Active</a> 
    </li> 
    <li class="nav-item"> 
    <a class="nav-link" href="#">Link</a> 
    </li> 
    <li class="nav-item"> 
    <a class="nav-link" href="#">Link</a> 
    </li> 
    <li class="nav-item"> 
    <a class="nav-link disabled" href="#">Disabled</a> 
    </li> 
</ul> 
</div> 

我可以添加一个类的div使堆叠丸可滚动吗？

Answer 1

是的，是否有可能， 只需添加类如anyclass 并给出一些CSS样式。 Live

.anyClass { 
    height:150px; 
    overflow-y: scroll; 
} 

.anyClass { 
 
    height:150px; 
 
    overflow-y: scroll; 
 
}

<div class=" col-md-2"> 
 
    <ul class="nav nav-pills nav-stacked anyClass"> 
 
    <li class="nav-item"> 
 
     <a class="nav-link active" href="#">Active</a> 
 
    </li>
