The dropdown-menu-end class in Bootstrap 5 navbar is not activating on hover as expected

My Bootstrap navbar has right-aligned dropdowns, but when I try changing the trigger to hover, the .dropdown-menu-end class doesn't work as expected.

I attempted using CSS for the hover effect:

.dropdown:hover .dropdown-menu {
  display: block;
  margin-top: 0;
}

and also tried using JavaScript:

$('.dropdown').mouseover(function () {
    if($('.navbar-toggler').is(':hidden')) {
        $(this).addClass('show').attr('aria-expanded', 'true');
        $(this).find('.dropdown-menu').addClass('show');
    }
}).mouseout(function () {
    if($('.navbar-toggler').is(':hidden')) {
        $(this).removeClass('show').attr('aria-expanded', 'false');
        $(this).find('.dropdown-menu').removeClass('show');
    }
 });

However, both methods resulted in the dropdown aligning to the left. I suspect it may be related to the use of display: block to trigger the hover effect, but I haven't been able to solve this issue yet.

The key CSS rule that is not being implemented when using your personalized event listener is as follows:

.dropdown-menu-end[data-bs-popper] {
    right: 0;
    left: auto;
}

This issue arises because the Bootstrap component does not assign that attribute. To rectify this, you can include it in your style sheet:

.dropdown:hover .dropdown-menu {
    display: block;
    margin-top: 0;
    right: 0;
    left: auto;
}
