A toolbar is shown at the top of the Page Layout section.
It exposes the following options:
•Add a new cell: this button is only available when a Pre-built page layout is selected. Clicking it adds a new cell to the page layout panel, at the first available empty position as defined by the rows/columns grid. The new cell occupies one grid cell only. The option is enabled when one or more available empty positions exist. Available positions are populated from the top left, then across the row.
•Remove the selected cell: this button is only available when a Pre-built page layout is selected. It is enabled when a cell is selected in the page layout panel. Invocation removes the selected cell from the panel. Any content therein is lost.
•Choose page layout: this button allows you to choose a page layout for the offer. Clicking it displays the Choose Page Layout dialog, which is covered separately.
•Hide/Show: clicking this button when the Page Layout section is shown causes it to be hidden.
A vertical ‘Page Layout’ is displayed to the left of the cell editor, at which you can click Show to redisplay the Page Layout section.
