output format for form display.

Hello,

I have a piece of code below for which I would like to get a formatted output like below. Is it possible to display below output format in hiCreateAppForm?

Code:

=================================================================

Characters=' ("Letters" "Letters" "Letters" "Letters" "Letters" "a" "b" "c" "d" "e"  "f" "g" "h" "i" "j" "k" "l" "m" "n" "o") ;

choices=foreach(mapcar elem Characters list(stringToSymbol(elem) elem))

mytoggle = hiCreateToggleField(
 ?name 'toppings
 ?prompt "Toppings"
 ?choices choices
 ?itemsPerRow 5
 ;?value ?( nil)
 ;?numSelect 1 )
)
hiCreateAppForm( ?name 'iceCreamForm
 ?formTitle "Ice Cream"
 ?callback "buildIceCreamCone()"
 ?fields list( mytoggle )
 ?help "cream" )

hiDisplayForm(iceCreamForm)

=================================================================
