Is there an easy way for the long list of checkboxes to display in column format with Gravity Forms?
So instead of
Please choose:

checkbox 1
checkbox 2
checkbox 3
checkbox 4
checkbox 5
checkbox 6

it will display as:
Please choose:

Checkbox 1        Checkbox 4
Checkbox 2       Checkbox 5
Checkbox3        Checkbox 6

SOLUTION:
Use one of the list classes  in the custom CSS class setting on the appearance tab of the field.

For 2 columns:  gf_list_2col

For 3 columns: gf_list_3col
