Navbar dropdown arrow does not work

[Constantinople4life]

Hello, the dropdown function on my website does not work and I need help debugging.

PHP Code:

<li class="nav-item dropdown">
          <a class="nav-link dropdown-toggle" href="game_store_console_section.php" id="navbarDropdown" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
            Consoles
          </a>
          <div class="dropdown-menu" aria-labelledby="navbarDropdown">
            <a class="dropdown-item" href="game_store_playstation.php">Playstation</a>
            <a class="dropdown-item" href="game_store_xbox.php">Xbox</a>
            <a class="dropdown-item" href="game_store_switch.php">Switch</a>
          </div>  
        </li> 


can anyone please help me find the problem?

Well. This is weird. At first glance, everything seems to be formatted correctly. Can you please privately email me the url to the page that isn't working so I can take a look?

Thank you for the awesome question!
