Php 引导导航开关未关闭wordpress中的菜单

我目前正在将我的静态网站转移到WordPress

我的引导点击导航菜单中的链接工作正常。burger菜单动画也很好，所以这告诉我JQuery在WordPress中工作得很好

但是，当我点击汉堡菜单时，它不会关闭。有人对此有答案吗

HTML代码：

<header id="header"> <!-- Start of header --> 
  <nav class="navbar navbar-expand-lg text-center navbar-light"> <!--   Sart of navigation --->
     <a class="navbar-brand" href="home.html"></a>

        <!-- Toggler -->
        <button class="navbar-toggler first-button" type="button" data-toggle="collapse" data-target="#navbarSupportedContent20"
          aria-controls="navbarSupportedContent20" aria-expanded="false" aria-label="Toggle navigation">
          <div class="animated-icon1"><span></span><span></span><span></span></div>
        </button>

        <!-- Collapsible content -->
        <div class="collapse navbar-collapse" id="navbarSupportedContent20">

          <!-- Links -->
          <ul class="navbar-nav mr-auto">
            <li class="nav-item active">
              <a class="nav-link" href="index.html">HOME</a>
            </li>
            <li class="nav-item">
              <a class="nav-link" href="portfolio.html">PORTFOLIO</a>
            </li>
            <li class="nav-item">
              <a class="nav-link" href="about-me.html">ABOUT ME</a>
            </li>
            <li class="nav-item">
              <a class="nav-link" href="#">CONTACT</a>
            </li>
          </ul>
          
        </div> <!-- End of collapsible content --->

      </nav> <!-- End of navigation --->
  </header> <!-- End of header --->

PHP代码：
