无法使用引导程序获取下拉菜单

我使用了getbootstrap中的教程，并按照它所说的那样做了，但它不工作，我点击它，什么也没有出现。我添加了HTML文件头，因为你们告诉我我的jquery和bootstrap CND可能有问题，所以这里是：
<!DOCTYPE HTML>
<html>
<head>
<title>
hah?
</title>
<link href="CSS/style.css" rel="stylesheet" type="text/css">
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.1/css/bootstrap.min.css" integrity="sha384-WskhaSGFgHYWDcbwN70/dfYBj47jz9qbsMId/iRN3ewGhXQFZCSftd1LZCfmhktB" crossorigin="anonymous">

<div class="container-fluid" id="container2">

你需要包括jQuery，popper和引导程序JS和CSS才能正常工作。这是一个有效的代码片段。
.btn-category{
background-color: #F7F7FA;
border-radius: 4px;
padding: 7px 15px;
margin: 35px 0 0 0;
border: 1px solid red;
color: red;
font-size: 12px;
}
.btn-category:focus {
outline: none;
}<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.3/umd/popper.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.1.1/js/bootstrap.min.js"></script>
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.1/css/bootstrap.min.css" rel="stylesheet"/>
<div class="dropdown">
<button class="btn-category dropdown-toggle" type="button" id="dropdownMenuButton" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
CATEGORIES
</button>
<div class="dropdown-menu" aria-labelledby="dropdownMenuButton">
<a class="dropdown-item" href="#">CURRENCY</a>
<a class="dropdown-item" href="#">TOP UP</a>
<a class="dropdown-item" href="#">ITEMS</a>
</div>
</div>
