<p><strong>NOTE:</strong> <em>This example demonstrates how to combine a menu built from existing markup with a menu built completely from JavaScript. The root menu in the left nav is constructed using markup and enables the user to navigate to different landing pages for each product category. If JavaScript is enabled, submenus are constructed and appended to the root menu. This allows the user to skip the product landing pages and proceed directly to a given property. Alternatively, you can <a href="leftnavfrommarkup.html">add submenus to a menu using markup</a></em></p>
