Automatic Data Block Creation

The Number of columns field controls the number of data blocks in the data area (each data block creates a column of text).

The Column gap field controls the horizontal distance between data blocks.

To create a block to hold side notes check the Enable box on the Side notes tab. A side note is some content that is associated with a point in the main text area, and appears alongside it. The content of side notes is assigned using the Content tab of a mapping.

To create a block to hold margin rules check the Enable box on the Margin rules tab. A margin rule is a vertical line drawn between two points in the main text. The start and end positions of the rule are determined by the Start Tag tab and End Tag tab of a mapping. Note that the thickness of the rule drawn does not depend on the width of the block. You can set the rule thickness in the Rule Weight field in the Format Options dialog, or by using the <marginrule-properties/> command.

The same controls are used to set the size and placement of side notes and margin rules. These are described below.

The Width field sets the width of the block.

The Gap field sets the horizontal distance between the block and the data block (or the next block when there are multiple notes).

The Position field controls the placement of the block relative to its data block. The Left and Right values have the obvious meanings. The meaning of Inside and Outside varies depending on the number of columns.

When there is a single column of text, Outside means closest to the outer edge when the pages are bound as in a book:

(and Inside obviously has the opposite meaning).

When there are multiple columns, Outside means closest to the edge of each separate page:

If there are more than two columns the positioning chosen for Inside and Outside may be inappropriate. In this case you can use the Edit menu to turn off Automatic Data Layout so the blocks can be positioned correctly.
