I am using the latest version of bootstrap. Kind of tried various things on my own and after that I thought I might find something on stackoverflow. But kind didn't get the thing. I mean how it works?

This is my code. I am not gonna add any custom style here since they didn't really work that well instead they created some error.

I also checked this post also Bootstrap - How to slide nav bar from left instead from top I tried all the answer from there but it didn't work for me.

The above CSS override does work. However, you have to wait for the height to transition first - causing a bit of a delay. The code below solves that.

 @media (max-width: 768px) {
        .navbar-collapse {
            position: fixed;
            top: 0;
            left: 0;
            padding-left: 15px;
            padding-right: 15px;
            padding-bottom: 15px;
            width: 75%;
            height: 100%;
        }

        .navbar-collapse.collapsing {
            left: -75%;
            transition: height 0s ease;
        }

        .navbar-collapse.show {
            left: 0;
            transition: left 500ms ease-in-out;
        }

        .navbar-toggler.collapsed ~ .navbar-collapse {
            transition: left 500ms ease-in-out;
        }
    }
