title: JQuery - TriState CheckBox
body: <p>I'm trying to find a tri-state checkbox plugin. However, every plugin I find relies on a hierarchy (like a folder structure) of elements. I just have a single checkbox element that I want to make a three-way checkbox. </p>
  
  <p>Does anyone know of a jquery plugin that will do this? I'm really surprised I didn't find one that works on <a href="http://plugins.jquery.com/" rel="noreferrer">http://plugins.jquery.com/</a>.</p>
  
  <p>Thank you for your input.</p>
