<h1>Very Advanced Recursive JSON Editor Example</h1>
<p>
This example demonstrates the use of a recursive schema - a Menu model, along with a slew
of other JSON Schema Editor and other desirable features:
</p>
<ul>
<li>Tabbed and table-formatted categories</li>
<li>Dynamic Labels</li>
<li>Editor-specific configuration (in the JSON Schema options objects) - e.g. no properties selector for the root node</li>
<li>Undo, Redo and Save functionality bound to buttons added to the root editor title</li>
<li>Hidden constant properties</li>
<li>Informational links</li>
<li>Various JSON Schema features around value validation ...</li>
<li>Commented-out code that shows how to load the schema and startval from a remote server (the example, of course, has those values hard-coded)</li>
</ul>
