isSelected() support for navigation with 3+ level

• Type: Improvement
• Status: Closed
• Priority: Minor
• Resolution: Fixed
• Affects Version/s: 5.1 EE (5.1.3)
• Fix Version/s: 5.1 EE SP1 (5.1.4)
• Component/s: Legacy Components > API, Themes
• Labels: None
• Environment: All

Currently, if there are 3 levels of pages (eg. Top Page > Sub Page > Details Page) and a user is on the Details Page, only the Top Page and the Details page will indicate that it's selected. This is accomplished through the NavItem's isSelected() method.

This improvement adds a new method to NavItem, isChildSelected(), that allows developers to check if Sub Page is selected.

Usage Example:

#if ($nav_item.isSelected() || $nav_item.isChildSelected())
#set ($nav_item_class = "selected")
#else
#set ($nav_item_class = "")
#end
