Choose how the CheckBox options are rendered: vertically, horizontally, or in mulitple columns.
Orientation determines whether the checkboxes are laid out vertically, horizontally, or in columns. If you choose the columns option, you can specify the 'snaking style'. This is either Left-to-Right-Top-to-Bottom (LRTB) or or Top-to-Bottom-Left-to-Right (TBLR).
Columns are not supported for ButtonList style.
For information on formating snaking columns, watch part 2 of the videos below. The easy way to set this format is to change the Column flow property (which is also in the CheckBox Properties section).
Dynamically Repopulate a CheckBox or RadioButton Control
In part 2, the CheckBox is populated with a much larger set of choices and a snaking layout (left-to-right, top-to-bottom) for the CheckBoxes is specified.
