A lightweight and easy-to-use jQuery plugin for creating cascading/chained dropdowns that dynamically populate corresponding select elements based on the previous selection.

How to use it:

1. To get started, load the following JavaScript and CSS files in the html page.

<script src="https://code.jquery.com/jquery-3.3.1.slim.min.js" 
        integrity="sha384-q8i/X+965DzO0rT7abK41JStQIAqVgRVzpbzo5smXKp4YfRvH+8abtTE1Pi6jizo" 
        crossorigin="anonymous"></script>
<script src="jquery.chainedTo.min.js"></script>

2. Create a group of child selects which are chained to parent selects. Child select options must have the data-available-with attribute which matches option values of parent select (regular expression is supported).

<select id="datacenter" class="form-control">
  <option value="am1">US North</option>
  <option value="am2" selected="selected">US South</option>
  <option value="em1">Europe</option>
</select>

<select id="desktoptype" class="form-control">
  <option value="xd_dedicated" data-available-with="am1,am2,em1">Dedicated Desktop</option>
  <option value="xd_pooled" data-available-with="em1">Pooled Desktop</option>
  <option value="xa_shared" selected="selected" data-available-with="am1,em1">Shared Desktop</option>
</select>

<select id="os" class="form-control">
  <option value="windows 7" data-available-with="am1+xd_dedicated,am2+xd_dedicated,em1+xd_dedicated,em1+xd_pooled">Windows 7</option>
  <option value="windows 10" selected="selected" data-available-with="am1+xd_dedicated,am2+xd_dedicated,em1+xd_dedicated">Windows 10</option>
  <option value="ws08" data-available-with="am1+xa_shared,em1+xa_shared">Server 2008 R2</option>
  <option value="ws16" selected="selected" data-available-with="am1+xa_shared">Server 2016</option>
</select>

<select id="bu" class="form-control">
  <option value="default" selected="selected" data-available-with="am1+*+*,am2+*+*,em1+*+*,ap1+*+*">Default</option>
  <option value="fin" data-available-with="am1+xd_dedicated+windows*,am2+xd_dedicated+windows 7">Financial</option>
  <option value="lac" data-available-with="am1+xd_dedicated+*,am2+xd_dedicated+*">Latin America</option>
</select>

3. Initialize the plugin and set the parent selectes the child selects should be chained to.

$("#desktoptype").chainedTo("#datacenter");
$("#os").chainedTo("#datacenter,#desktoptype");
$("#bu").chainedTo("#datacenter,#desktoptype,#os");
