What potential pitfalls should be considered when using the setRenderInvisible method in Zend_Navigation in PHP?

When using the setRenderInvisible method in Zend_Navigation, it's important to consider that setting elements to render as invisible may affect the layout and functionality of the navigation menu. It can lead to unexpected behavior or broken links if not handled carefully. To mitigate this, ensure that invisible elements are properly styled or excluded from user interaction.

php 
// Example of setting a navigation element to render as invisible
$navigation = new Zend_Navigation();
$page = new Zend_Navigation_Page_Uri(array(
    'label' => 'Home',
    'uri' => '/',
    'visible' => false // Set element to render as invisible
));
$navigation->addPage($page);
