Prior to the 1.9 release, the menu helper
(Zend_View_Helper_Navigation_Menu) did not
render sub menus correctly. When onlyActiveBranch
was TRUE and the option renderParents
FALSE, nothing would be rendered if the deepest active
page was at a depth lower than the minDepth option.
In simpler words; if minDepth was set to '1' and the active page was at one of the first level pages, nothing would be rendered, as the following example shows.
Consider the following container setup:
<?php
$container = new Zend_Navigation(array(
array(
'label' => 'Home',
'uri' => '#'
),
array(
'label' => 'Products',
'uri' => '#',
'active' => true,
'pages' => array(
array(
'label' => 'Server',
'uri' => '#'
),
array(
'label' => 'Studio',
'uri' => '#'
)
)
),
array(
'label' => 'Solutions',
'uri' => '#'
)
));
The following code is used in a view script:
<?php echo $this->navigation()->menu()->renderMenu($container, array(
'minDepth' => 1,
'onlyActiveBranch' => true,
'renderParents' => false
)); ?>
Before release 1.9, the code snippet above would output nothing.
Since release 1.9, the _renderDeepestMenu() method in
Zend_View_Helper_Navigation_Menu will accept
active pages at one level below minDepth, as long as
the page has children.
The same code snippet will now output the following:
<ul class="navigation">
<li>
<a href="#">Server</a>
</li>
<li>
<a href="#">Studio</a>
</li>
</ul>
