Editing the page grid of a Page comprises several tasks:

Selecting a page grid

Your page needs a page grid in order to place the content.

Open the Content tab of the Page content and select the Page grid in the Page Layout dropdown list.

The Page grid editor will show link lists for each placement of the page grid, where you can add content to.

Adding content to placements

The Page grid editor shows for each placement of the page grid a link list where you can add existing content or create new content.

Section 4.6.5, “Editing Link Lists” describes how you add or create content in the link list.
