The number of cells in the gird are controlled via $GridRows and $GridColumns. The cells can each be given a label via $GridLabels, which are drawn in $GridLabelFont at $GridLabelSize. The overall grid and labels are drawn in $GridColor and with $GridOpacity.
All these adjustments can be accessed via the Grid Properties pop-over which is accessed by the grid icon on any currently selected adornment.
The image shows a 2 row, 2 column grid with labelled cells; all other settings are default. Transparent adornments may draw a border and grids.
The use of a grid does not affect the OnAdd action of the adornment, which applies to a note regardless of where on the grid it is placed.
The placement of notes by a smart adornment is not aware of a grid. The smart process will use the adornment as a whole, ignoring grid assignments. Therefore grids are not ideally used with smart adornments.
The grid icon is not displayed when the adornment is part of a multiple selection.
