What are some best practices for handling invisible elements in Zend_Navigation when rendering menus in PHP?

When rendering menus with Zend_Navigation in PHP, invisible elements (such as those with the 'invisible' flag set) can cause unexpected behavior in the menu structure. To handle this, it is best practice to filter out these invisible elements before rendering the menu to ensure a clean and accurate menu display. 

// Filter out invisible elements before rendering the menu
$container = new Zend_Navigation($config);

// Filter out invisible elements
$visiblePages = array_filter($container->findAllBy('visible', true));

// Render the menu with only visible elements
echo $this->navigation()->menu()->renderMenu($visiblePages);
