Responsive Dropdown/Off-canvas Navigation In Vanilla JavaScript – Menue

Preview:

Description:

Menue is a responsive, multi-level, cross-platform dropdown/off-canvas navigation system for both desktop and mobile.

Features:

• Auto expands the nav to the full width and sticks it to the top of the page on scroll.
• Auto transforms the horizontal navbar into an off-canvas side nav on mobile & tablet devices.
• Supports unlimited levels of sub-menus. Based on nested HTML lists.

How to use it:

1. Import the compiled stylesheet and JavaScript in the document.

<link rel="stylesheet" href="style.css" />
<script src="menue.js"></script>

2. Add both desktop and mobile menus to your web page.

<div class="desktop-menu">

      <li>
        <a href="#main1">Menu Item 1</a><span class="item-toggle-button">Toggle</span>
        <div class="secondary-nav">
