Not quite sure about this, as I am implementing it for the first time... But, it appears strange to me that the view_helper_namespace is a constant... This more or less prohibits extending Zend_View_Helper_Navigation to fit my needs with a extension on Zend_View_Helper_Navigation_Menu.
Indeed, by making it a protected var, I could just set another view_helper namespace and create my App_View_Helper_Navigation_Menu without any further issues.
I figure there is a reason for it to be a constant though... And I am curious to know it ? Or I am missing something... And then it would be nice to know what.
The objective would be to be able to display the siblings of the active menu element's parent... Something like this :
Administration '|- Settings '|- Users .....'|- Groups .....'|- Users......[active] '|- Accounts
Right now, when Administration > Users > Users is active, Settings and Accounts are not visible... Which is not very userfriendly.
I know this is not the place to post questions about how ZF works... But I believe this explains why I want to extend Zend_View_Helper_Navigation and Zend_View_Helper_Navigation_Menu.
