Cool Multi-level Context Menu With jQuery And CSS3

A pretty cool multi-level context menu to override the default browser right-click menu. Built using JavaScript (jQuery) and CSS/CSS3.

Features:

• Pretty nice CSS3 animations.
• Cool CSS filters.
• Auto-reposition if it overflows the screen.
• Theme switcher.
• SEO-friendly. 

How to use it:

1. Create a multi-level context menu from nested HTML lists as follows:

<ul class="context">
  <li class="top">
    Menu 1
    <ul class="context sub"> 
      <li title="Chosen: Red">
        Menu 1-1
      </li>
      <li title="Chosen: Xtra Large">
        Menu 1-2
      </li>
    </ul>
  </li>
  <li class="hilight">
    Menu 2 (Highlighted)
  </li>
  <li>
    Menu 3
  </li>
  <!-- Separator -->
  <li class="div"></li>
  <li>
    Menu 4
    <ul class="context sub"> 
      <li class="hilight">
        Menu 4-1
      </li>
      <li>
        Menu 4-2
      </li>
    </ul>
  </li>
</ul>

2. Create two input fields for the theme switcher.

<div class="colors">
  <h4>Theme Switcher</h4>
  <input type="color" name="c1" id="c1" value="#673ab7"/>
  <input type="color" name="c2" id="c2" value="#3f51b5"/>
</div>

3. The required CSS rules for the context menu. Feel free to create your own styles by overriding the variables at the beginning of the following CSS snippets.

:root {
  --bg: #24262d;
  --text: #dfe3ff;
  --color1: #673ab7;
  --color2: #3f51b5;
