I. Intro

🔖

Availability: My Document Library is in beta and is not yet available to all users.

Platform requirements: These steps can only be performed on the desktop app or web version.

For Docs format pages in Wiki or My Document Library, you can quickly add a sub-page by creating a new sub-doc or converting content in the document into a sub-document.

Note :

Users with edit permission for a page can create sub-docs.

Sub-docs refer to sub-pages that are of the document type.

II. Steps

From Wiki or My Document Library, open a page in the Docs format for which you have edit permission. You can choose to create a new sub-doc or convert existing content on the page into a sub-doc.

Create a new sub-doc

Enter / on a blank line of the document, or press Space and enter / anywhere in the text, and select Sub-doc. You can also find this option from the toolbar that appears when you click the + icon or the ⋮⋮ icon. For more details, see Use toolbars in Docs.

After the sub-doc is created, the selected content in the document will be deleted and replaced with the sub-doc link. The sub-doc will appear in the table of contents of the wiki space or My Document Library.

III. FAQs

Why can't I find the sub-doc option on my page?

This option is only available for pages in Docs format in Wiki and My Document Library. Check whether the page you're on is in one of those two locations.

I made a mistake. How do I undo or redo changes?

On the page, press Ctrl + Z (Windows) or Command + Z (Mac) to restore the content that is converted into a sub-doc. The sub-doc that is created won't be deleted and you need to manually delete the sub-doc.

Press Ctrl + Y (Windows) or Command + Shift + Z (Mac) to redo your action and restore the sub-doc link.

How do I insert a link to a sub-document in the parent document?

If you only need to reference the sub-document in the parent document, copy the link of the sub-document and paste it into the parent document.

To link text in the parent document to the sub-document, add a hyperlink to the text. For more details, see Add hyperlinks in Docs.

Will the sub-doc be deleted if I delete its link?

No, you can still find the sub-doc in the table of contents of Wiki or My Document Library.

Can I create different types of sub-pages from a page?

If you want to create other types of sub-pages, you can click the + icon next to a page in the Wiki table of contents and selecting a document type.
