I'm trying to have a drop down menu within a navbar; however, it only displays until the limit of my navbar when, ideally, id like it to be "in front" of the navbar so to speak.
Dropdown is cut off
I am new to html and CSS so my exploration is somewhat limited. I have implemented one of bootstrap's navbar's and also used their dropdown button html. I expected this to work okay but, as stated, the dropdown seems to be bound within the navbar (assuming this is because it is within the navbar div?) I have also attempted to follow w3schools guide but I didn't succeed with that either.
Sidenote: because of the limited visibility, the "my account" button logs the user out, this is intentional for now lmao.

<body>      
    <nav class="navbar navbar-expand-lg bg-light">
        <div class="container-fluid">
        <a class="logo" href="/"><img src="static/Logo_2.png" alt="Logo"></a>
        <div class="navbar-nav">
            {% if not session["id"] %}
                <a class="nav-link" href="login">Log In</a>
            {% endif %}
            {% if session["id"] %}
                <a class="nav-link" href="languages">Languages</a>
                <a class="nav-link" href="faq">FAQs</a>
                <div class="dropdown">
                    <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton1" data-bs-toggle="dropdown" aria-expanded="false">

your example should be cut down to just the minimum that displays the issue. you have extra classes, some ASP-like code, etc - none of that is needed and just makes it harder to diagnose.
the issue appears to be that your submenu is contained inside the top-level .navbar element, but you are constraining that to have a height of 100 (and you should include the metric here - 100px? 100cm?) with overflow being hidden. this means that the submenu gets cut off.
you could just remove those constraints.
a better solution would involve a rewrite, so the submenu items are positioned absolutely, in a relatively-positioned placeholder. there are examples of this online. example: https://gist.github.com/SamWM/901853
