如何将Bootstrap导航栏集成到WordPress主题中

<nav class="navbar navbar-default" role="navigation"> 
<!-- Brand and toggle get grouped for better mobile display --> 
  <div class="navbar-header"> 
    <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-ex1-collapse"> 
      <span class="sr-only">Toggle navigation</span> 
      <span class="icon-bar"></span> 
      <span class="icon-bar"></span> 
      <span class="icon-bar"></span> 
    </button> 
    <a class="navbar-brand" href="#">Brand</a> 
  </div> 
  <!-- Collect the nav links, forms, and other content for toggling --> 
  <div class="collapse navbar-collapse navbar-ex1-collapse"> 
    <ul class="nav navbar-nav"> 
      <li class="active"><a href="#">Link</a></li> 
      <li><a href="#">Link</a></li> 
      <li class="dropdown"> <a href="#" class="dropdown-toggle" data-toggle="dropdown">Dropdown <b class="caret"></b></a> 
        <ul class="dropdown-menu"> 
          <li><a href="#">Action</a></li> 
          <li><a href="#">Another action</a></li> 
          <li><a href="#">Something else here</a></li> 
          <li><a href="#">Separated link</a></li> 
          <li><a href="#">One more separated link</a></li> 
        </ul> 
      </li> 
    </ul>
  </div>
</nav>

<nav role="navigation">…</nav>
