The Page element panel is where you set up a page element. It opens when you click one in the work area, and it works just like the Label element panel, with the same sections: Text, Barcode, Image, Grid, Pattern, Line and Properties.

What's different comes from the element being on the page, not on a label:

Differences
No data	Data source on the strip is dimmed, there are no fields to add, and no color or picture can come from your data.
References	The ones about a label - its column and row, its number, its label set's name - aren't offered. The ones about the page are: the current page, the total pages, the first and last label on the page.
The path	The document, then the element: there's no label set.
Advanced	Instead of Conditional visibility, the options that say where and when the element appears: Show on, Skip first page, Skip last page and Position.

The page options
Show on	All pages, Even pages only, Odd pages only, First page only or Last page only.
Skip first page, Skip last page	Leaves it off the first or last page.
Position	On top of labels or Behind labels.

Move to, Fit and the grid work on the paper for a page element, not on a label. Bring to front also sets it On top of labels, and Send to back sets it Behind labels.
