Falcon used the Bootstrap's .navbar-expand{-sm|-md|-lg|-xl|-xxl} classes in .navbar-vertical element to decide when the navbar vertical will expand or not.

<nav class="navbar navbar-vertical navbar-expand-xl navbar-light">

  <!-- Content-->
  <div class="collapse navbar-collapse">
    <div class="navbar-vertical-content scrollbar">

      <!-- Collapsible content-->
    </div>
  </div>
</nav>

From your project directory, If you are using gulp version open src/js/config.js or if you are using directly from the public folder open public/assets/js/theme.js and set isNavbarVerticalCollapsed: true of CONFIG object to collapse the Vertical Navigation by default

const CONFIG = {
  isNavbarVerticalCollapsed: false,
  ...
};

Normally, links in navbar vertical may contain icons, texts, badges and indicator icons. By default each elements in navbar vertical's links are vertically centered with each other. Navbar vertical's top parent link example:

<a class="nav-link" href="#">
  <div class="d-flex align-items-center">
    <span class="nav-link-icon"><span class="fas fa-chart-pie"></span></span>
    <span class="nav-link-text">Dashboard </span>
    <span class="badge rounded-pill badge-soft-success ms-2">New</span>
  </div>
</a>

If you have long texts or you want to update the alignment, you can customize by removing align-items-center class or adding Bootstrap align-items-* helper classes.

Child link example:

<a class="nav-link" href="#">
  <div class="d-flex align-items-center">
    Dashboard
    <span class="badge rounded-pill badge-soft-success ms-2">New</span>
  </div>
</a>

Add dropdown-indicator class to .nav-link element to show arrow icon to the right side of the link text.

<a class="nav-link dropdown-indicator" href="#">

  <!-- link content-->
</a>

const navbarVerticalToggle = document.querySelector(.navbar-vertical-toggle);
navbarVerticalToggle.addEventListener('navbar.vertical.toggle', function () {
  // do something...
})

<nav class="navbar navbar-vertical navbar-expand-xl navbar-light navbar-inverted">

  <!-- Content-->
  <div class="collapse navbar-collapse">
    <div class="navbar-vertical-content scrollbar">

      <!-- Navbar content-->
    </div>
  </div>
</nav>

You can change background-color by adding .bg-* utility classes in .navbar-collapse element or you can update globally using the SCSS variable which is described in SCSS section below.

<div class="collapse navbar-collapse bg-1000">
   <div class="navbar-vertical-content scrollbar">
