Checkboxes and RadioButtons - Columnar Layout
Description
There is an option to lay out the choices in a checkbox or radiobutton group in multiple rows and columns. You can specify the 'snaking' style - left-to-right-then-top-to-bottom, or top-to-bottom-then-left-to-right.
The following image shows radiobutton choices in a mult-column list with the snaking style set to left-to-right.
