I can't get my navbar to show an edit profile dropdown after logged in - receiving an error as soon as a log in as an artist (artists=user).

Global variables from app.js
app.use((req, res, next) => {
console.log(req.session);
res.locals.currentUser = req.user;
res.locals.success = req.flash('success');
res.locals.error = req.flash('error');
next();
})
How do I structure my navbar ejs so I can allow logged-in artists to "edit" their user profile? I'm thinking it has something to do with my global variables on app.js so I've included a snippet of the file.
Figured it out-- I had to change the name of the ejs variable because I had already defined currentUser:
From:
href="/artists/<%=artist.id%>/edit">Edit profile
To:
href="/artists/<%=currentUser.id%>/edit">Edit profile
The artist's id had already been passed into currentUser so I was able to pull it out of there.

I have a file, and there is a fragment for navbar. In the navbar, we have listItems, and based on the click of those listItems, we plan to open another subnavigationbar below it.
To achieve this, I have the following code:
<!DOCTYPE html>
<html xmlns:th="https://www.thymeleaf.org"
xmlns:sec="https://www.thymeleaf.org/thymeleaf-extras-springsecurity5">
<body>
<div>
<div th:fragment="navbar">

aria-label="Toggle navigation">

</button>

var projects = document.getElementById("movies");
var subNavBar = document.getElementById("subNavbarId"); //Failure

})
</script>
</div>
<div class = "subNavClass" id="subNavbarId" th:fragment="subnavbar" style="display: none;">

style="background-color: #F5F5F5;">
<div class="collapse navbar-collapse">

<ul class="navbar-nav mr-auto mt-2 mt-lg-0">

</ul>

subNavBar.addEventListener("mouseleave", function() {
subNavBar.style = "display:none;"
})
</script>
</div>
</div>
</body>
</html>
I want to have a scenario, where I click the "movie" on the navbar, and I get a subnavbar displayed with movieList. Similarly, when I click somewhere outside, the subnavbar fades away.
Guide me here.
PS: total noob
your subNavBar.style = "display:block;" looks wrong.
it should be subNavBar.style.display = "block";
According to the Bootstrap documentation, you can use a dropdown :
<link href="https://cdn.jsdelivr.net/npm/bootstrap#5.1.3/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-1BmE4kWBq78iYhFldvKuhfTAU6auU8tT94WrHftjDbrCEXSU1oBoqyl2QvZ6jIW3" crossorigin="anonymous">
<div class="btn-group">
<button type="button" class="btn btn-primary dropdown-toggle" data-bs-toggle="dropdown" aria-expanded="false">
Action
</button>
<ul class="dropdown-menu">
<li><a class="dropdown-item" href="#">An action</a></li>
<li><a class="dropdown-item" href="#">Another action</a></li>
<li><a class="dropdown-item" href="#">Something else here</a></li>
<li><hr class="dropdown-divider"></li>
<li><a class="dropdown-item" href="#">Separated link</a></li>
</ul>
</div>

By the way, avoid changing css with javascript. You can make a css class and toggle it. Because you use Bootstrap, you can toggle the d-none provided class :
subNavBar.classList.toggle("d-none");
How can you collapse the menu of a Bootstrap burger when you click on a scrollspy link?
When viewing my website on a smartphone, the bootstrap nav is reduced to a burger menu. If you click on a link that leads to a specific place in my index.html (such as #aboutMe) and not to an external page, then the navigation remains unfolded. I want it to collapse again afterwards.

I already looked at: How to hide collapsible Bootstrap navbar on click
And: Bootstrap panel-collapse collapses when you click on a link inside it is clicked
but nothing worked.
I'm using the latest version of jQuery and Bootstrap version 5.0.1:

In Jquery simply trigger click on the navbar-toggler button when link is clicked
$('.nav-link').click(function(){
$('.navbar-toggler').click();
});
$('.nav-link').click(function(){
$('.navbar-toggler').click();
});

You first need to select all .nav-link excluding .dropdown-toggle.
Then, assign an event listener to toggle the .navbar-collapse on click:
$(document).ready(() => {
let $navlinks = $('.nav-link').not('.dropdown-toggle');
// console.log($navlinks)
$navlinks.click((e) => {
$(e.target).closest('.navbar').find('.navbar-collapse').collapse('toggle')
})
})

I have a navbar that has a hamburger toggle when going below a certain screensize. My problem is that the navbar goes down (expands properly) but does not go up again (collapse).
I tried to check other forums and same questions about the same issue but nothing helped. I definitely need some refreshment as I haven't been coding JS for a while.

I made it work by commenting in my application.html.erb file the following line of code:
<script src="https://code.jquery.com/jquery-3.3.1.slim.min.js" integrity="sha384-q8i/X+965DzO0rT7abK41JStQIAqVgRVzpbzo5smXKp4YfRvH+8abtTE1Pi6jizo" crossorigin="anonymous"></script>
Thanks all for your help!
How I worked? I started commenting all the lines out to see which impact it had on my navbar and my website and I found out it was the one making it work not properly.
I am trying to add a navbar to this website, but for some reason it is not functioning how I thought it would. The main problem I am trying to solve is getting the dropdown menu to actually display the list. It visually looks like the menu is already expanded, but I don't know if that has anything to do with why it is not working. Currently, the collapsed version will open from the hamburger menu only because of the CSS I added. Without the CSS, that navbar will expand, but immediately collapse again. Things I have tried:
I have tried to switch the order that I include Bootstrap.js/css and jQuery, but that has no effect on it.
I have also tried to switch versions because I am not sure what is compatible with what, but that has not been successful.
The one thing that did work was using an old version of bootstrap, but I would like to use 4.0 or higher if that is possible.
I would appreciate it is someone could help me figure out why this is not working. Thanks!

That's because your bootstrap.js is version 3.3.7, and this is not how you implement sub-menu (on bootstrap 3). Although, If you're using bootstrap 4 already, you should consider updating your bootstrap.js to version 4.0.0 (And you should use the same versions of bootstrap.js and bootstrap.css to avoid unexepected bugs (like you just had).
