Organize site Spaces by grouping them under Collections.
With a site full of different Spaces, it can be helpful to categorize them within folders. This is where Admins can utilize Collections: a group of Spaces collected into one place that allows Admins to organize and manage Spaces within the left sidebar.
Change the order of Spaces under each Collection
Admins can organize the listing order of the spaces under each Collection.
Login with your admin account > navigate to the top header > click on your profile image > access the Administration
Access the Design Studio on the left, select the Spaces tab > Find the Collection to organize > Click [...] to the right of the Collection name > Organize
Drag and drop the Spaces to adjust the order of Space inside that Collection, which will be displayed on the left sidebar. The order is also mimicked in the Collection Page.
Save changes.
Move a Space from one Collection to Another
Login with your admin account > navigate to the top header > click on your profile image > access the Administration
Access the Content section on the left, select the Spaces tab > Find and select the Space that you would like to move to another Collection > click [...] > click Settings. This takes you to the Space Setting page
From the Space settings page, click on Settings from the left-side menu > scroll down and pick the Collection from the suggestion list > Update
