The navigation elements (TOC, navmenu) are typically set using the toc and navmenu page variables in the Front Matter Defaults (or for a particular page in its Front Matter). The variables should point to data files with the correct structure in the /_data folder.
The defaults for this project are shown below. These demonstrate how to set the global values, and how to provide different values for specific folder paths and collections (types).
defaults:
- # Global default is use structures in /_data/toc.yml and /_data/navmenu.yml
scope:
path: ""
values:
toc: toc
navmenu: navmenu
- # Specify values for a collection using the scope type "test_collection"
scope:
path: ""
type: "test_collection"
values:
toc: toc_test_collection
navmenu: navmenu_test_collection
- # Specify values for particular folder path using the scope > path variable.
scope:
path: "test_section"
type: "pages"
values:
toc: toc_test_section
navmenu: navmenu_test_sectionCollections are not required in order to give sets of topics common navigation - you can simply group the topics in folders and sepcify the path in the scope.
