Stage
Automatically stage all pages and files in a designated folder. From the left tree, select the folder you wish to stage the contents of. Click the ... menu next to + Add, then click Stage. There's no confirmation form to fill out — this applies immediately.
Warning:
Staging will apply to all pages and files within a selected folder. Make sure you are aware of the folder's contents — including any files that you wish to remain in draft or publish — before you click Stage.
Note:
On a large folder, staging can take a few moments to finish. Avoid navigating away until it completes.
