Sticky Mobile-friendly Navigation Menu With jQuery

This is a sticky responsive nav menu built using jQuery and CSS3 that automatically converts the regular dropdown nav into a mobile-friendly off-canvas menu. The mobile menu will slide from the right hand side of the screen while blurring the main content.

How to use it:

1. Create a normal html list based dropdown nav for your website. In this case, we're going to create a multi-level dropdown nav from nested HTML unordered lists as these:

<div id="navigation" class="navigation">
  <nav id="nav">
    <ul>
      <li><a href="#">LINK 1</a></li>
      <li><a href="#">LINK 2</a></li>
      <li><a href="#">LINK 3.1</a>
        <ul>
          <li><a href="#">LINK 3.2</a>
            <ul>
              <li><a href="#">LINK 3.2.1</a></li>
              <li><a href="#">LINK 3.2.2</a></li>
              <li><a href="#">LINK 3.2.3</a></li>
            </ul>
          </li>
          <li><a href="#">LINK 3.3</a></li>
          <li><a href="#">LINK 3.4</a></li>
        </ul>
      </li>
      <li><a href="#">LINK 4</a></li>
      <li><a href="#">LINK 5</a></li>
      ...
    </ul>
  </nav>
</div>

2. Create a button to toggle the off-canvas menu on mobile view.

<div id="button-box" class="button-box">
  <button type="button" id="toggle-nav" class="toggle-nav">MENU<span>&#9776;</span></button>
</div>

3. The main CSS/CSS3 styles.

#button-box {
  display: flex;
  flex-direction: row;
  height: 64px;
  position: absolute;
  right: 0;
  top: 0;
  width: 96px;
}

#toggle-nav {
  border: 0;
  height: 64px;
  line-height: 64px;
  padding: 0;
  position: relative;
  text-indent: -99999px;
  width: 48px;
}

#toggle-nav span {
  display: block;
  font-size: 1.7rem;
  left: 25%;
  position: absolute;
  text-indent: 0;

  border-left: 1px solid #a1a1a1;
  content: '\22EE';
  font-size: 1.3rem;
  height: 48px;
  position: absolute;

  width: 32px;
}

#nav .li-has-Children .ul-visible { border-top: 1px solid #a1a1a1; }

#overlay {

  visibility: hidden;
  width: 100%;
  z-index: +1;
}

#overlay.visible {
  opacity: 1;
  visibility: visible;
}

@media only screen and (min-width: 1200px) {

#button-box {
  position: relative;
  width: 48px;
}

#toggle-nav { display: none; }

#navigation {
  box-shadow: none;
  float: left;
  height: 64px;
  position: relative;
  top: 0;
  width: calc(100% - 200px - 48px);
}

#nav {

  overflow: hidden;
  position: relative;
  width: 100%;
}

#nav ul {

}

#nav ul li {

  z-index: +1;
}

#nav ul li .hasChildren {

4. The main JavaScript to enable the navigation. Just add the following JavaScript snippets after jQuery library and done.

<div id="button-box" class="button-box">
  <button type="button" id="toggle-nav" class="toggle-nav">MENU<span>&#9776;</span></button>
</div>

<div id="button-box" class="button-box">
  <button type="button" id="toggle-nav" class="toggle-nav">MENU<span>&#9776;</span></button>
