Convert Bootstrap 5 Navbar Into Offcanvas Menu

A Bootstrap extension that converts the regular Bootstrap 5 navbar into an offcanvas sidebar menu instead of a toggleable dropdown menu.

How to use it:

1. Add the CSS class main-navigation to your navbar component.

<nav id="navbar_top" class="navbar navbar-expand-lg navbar-dark bg-primary main-navigation" id="navbar">
  <div class="container">
    <a class="navbar-brand" href="#">LOGO</a>
    <button class="navbar-toggler" type="button">
    <span class="navbar-toggler-icon"></span>
    </button>
    <div class="overlay d-flex d-lg-none"></div>
    <div class="order-lg-2 bg-primary d-lg-flex w-100 sidebar pb-3 pb-lg-0">
      <ul class="navbar-nav ms-lg-auto mb-2 mb-lg-0">
        <li class="nav-item">
          <a class="nav-link px-3 px-lg-2 active" aria-current="page" href="#">
            <svg width="1.5em" height="1.5em" viewBox="0 0 16 16" class="bi bi-house-fill" fill="currentColor" xmlns="http://www.w3.org/2000/svg">

<link rel="stylesheet" href="/path/to/cdn/bootstrap.min.css" />
<link rel="stylesheet" href="/path/to/css/style.css" />
<script src="/path/to/cdn/bootstrap.bundle.min.js"></script>
