<h1>Setting Menu Configuration Properties At Runtime</h1>
<div class="exampleIntro">
<p>
This example demonstrates how to set MenuItem configuration properties at
runtime and listen for the changes through the "configChanged" event.
</p>
<p id="clicknote">
<em>Note:</em> By default clicking outside of a menu will hide it.
Additionally, menu items without a submenu or a URL to navigate to will hide their
parent menu when clicked. Click the "Show Menu" button below to make the menu
visible if it is hidden.
