javascript - 折叠菜单活动当前选项

Question

我有带有下拉选项的引导侧栏菜单，我想在用户单击它时激活下拉菜单选项，该选项将打开而不是折叠，我该怎么做？

<ul class="list-unstyled components mb-5">

      <li class="active">

        <a href="#homeSubmenu" data-toggle="collapse" aria-expanded="false" class="dropdown-toggle">User
          Management</a></li>
        <ul class="collapse list-unstyled points" id="homeSubmenu">
          <li class="active">
            <a href="../createuser.html">Create User</a></li>
          <li>
            <a href="../edituserprofile.html">Edit User Profile</a>
            </li>
          <li>
            <a href="../deleteuser.html">Delete User</a>
          </li>
          <li>
            <a href="../activateuser.html">Activate & De-Activate User</a>
          </li>

        </ul>

这是html代码。
