                <li>Create TreeGrid from HTML table</li>
                <li>Simple and flexible javascript</li>
                <li>Compatible with bootstrap</li>
                <li>Ability to save the state of the tree</li>
                <li>Events support</li>

            </ul>            
            <h2>Usage</h2>
            <p>Step 1. Initialize plugin</p>
            <pre><code>
&lt;script type="text/javascript" src="js/jquery.js"&gt;&lt;/script&gt;
&lt;script type="text/javascript" src="js/jquery.treegrid.js"&gt;&lt;/script&gt;
&lt;link rel="stylesheet" href="css/jquery.treegrid.css"&gt;

&lt;script type="text/javascript"&gt;
  $('.tree').treegrid();
&lt;/script&gt;</code></pre>
            <p>Step 2. Make table</p>
            <pre><code class="html">
&lt;table class="tree"&gt;
	&lt;tr class="treegrid-1"&gt;
		&lt;td&gt;Root node&lt;/td&gt;&lt;td&gt;Additional info&lt;/td&gt;
	&lt;/tr&gt;
	&lt;tr class="treegrid-2 treegrid-parent-1"&gt;
		&lt;td&gt;Node 1-1&lt;/td&gt;&lt;td&gt;Additional info&lt;/td&gt;
	&lt;/tr&gt;
	&lt;tr class="treegrid-3 treegrid-parent-1"&gt;
		&lt;td&gt;Node 1-2&lt;/td&gt;&lt;td&gt;Additional info&lt;/td&gt;
	&lt;/tr&gt;
	&lt;tr class="treegrid-4 treegrid-parent-3"&gt;
		&lt;td&gt;Node 1-2-1&lt;/td&gt;&lt;td&gt;Additional info&lt;/td&gt;
	&lt;/tr&gt;
&lt;/table&gt;

	  </code></pre>
            <p>Step 3. See result</p>

            <table class="tree">
                <tr class="treegrid-1">
                    <td>Root node</td><td>Additional info</td>
                </tr>
                <tr class="treegrid-2 treegrid-parent-1">
