WP API Menus
This plugin extends the WordPress JSON REST API with new routes for WordPress registered menus
The new routes available will be:
/menuslist of every registered menu./menus/<id>data for a specific menu./menu-locationslist of all registered theme locations./menu-locations/<location>data for menu in specified menu in theme location.
Currently, the menu-locations/<location> route for individual menus will return a tree with full menu hierarchy, with correct menu item order and listing children for each menu item. The menus/<id> route will output menu details and a flat array of menu items. Item order or if each item has a parent will be indicated in each item attributes, but this route won't output items as a tree.
You can alter the data arrangement of each individual menu items and children using the filter hook json_menus_format_menu_item.
An important note on WP API V2:
In V1 the routes are located by default at wp-json/menus/ etc.
In V2 the routes by default are at wp-json/wp-api-menus/v2/ (e.g. wp-json/wp-api-menus/v2/menus/, etc.) since V2 encourages prefixing and version namespacing.
