Configuring Plugin Features

Several components of the navigation plugin can be enabled / disabled programmatically.

The current feature list includes:

Feature	Description	Default
manager	Navigation manager (the "Edit Order" screens)	On
widget	Content Nav widget	On
links	Include external navigation links with page menus	On
primary	Primary navigation settings screen	Off

Disabling Plugin Features

If your install does not require one or more of these built-in features, they can be disabled by adding a constant to your wp-config.php or theme's function.php file:

<?php
define( 'BU_NAVIGATION_SUPPORTS_<all caps feature slug>', false );

For example, to disable the "Edit Order" screens for hierarchical post types, you could add the following:

<?php
define( 'BU_NAVIGATION_SUPPORTS_MANAGER', false );

These constants are best placed in your wp-config.php file, where they will take affect install-wide. To enable features for specific themes, there is a better option.

Using the Theme Features API

Theme authors may wish to register support for navigation plugin features that are off by default or require theme participation. The most common use case is to support the primary navigation settings screen.

Add the following line to your theme's functions.php file:

<?php
add_theme_support( 'bu-navigation-primary' );
