Answer 1

В приведенном коде нет возможности узнать какой версии bootstrap.css.

Так как используется bootstrap/4.0.0-alpha.6, то и css должна быть соответствующей версии.

Если ее брать с CDN - все работает:

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/css/bootstrap.min.css" integrity="sha384-rwoIResjU2yc3z8GV/NPeZWAv56rSmLldC3R/AZzGRnGxQQKnKkoFVhFQhNUwEyJ" crossorigin="anonymous"> 
 
<div class="dropdown"> 
  <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"> 
        Dropdown button 
      </button> 
  <div class="dropdown-menu" aria-labelledby="dropdownMenuButton"> 
    <a class="dropdown-item" href="#">Action</a> 
    <a class="dropdown-item" href="#">Another action</a> 
    <a class="dropdown-item" href="#">Something else here</a> 
  </div> 
</div>
