When space numbering is enabled, all pages within the space will have page numbering enabled. Space numbering is an option available to space admins only.
Login as an administrator or space admin.
Navigate to Space tools and choose Add-ons or Apps.
Choose the Numbered Headings tab.
Enable / disable the toggle on this page.
When space numbering is configured for a space, you might want to exclude one or more pages from automatically being numbered. You can do that by going to the page and deselecting the button.
Using the button also enables the possibility to add custom formatting to a page in a space where space numbering is enabled, this overrides the default numbering scheme.
If you are adding content via automation and you want a single page to be excluded from numbering, refer to the API documention.
