Checkboxes - 2 columns instead of 1?

I'm not clear, are you referring to displaying checkboxes in a table? With the checkbox in one column and the text displayed with the checkbox in another column? If so, no there isn't anyway to do that currently.

The form output is set as far as markup goes. You have to use CSS to style and make changes to the display of the form. You can't edit the markup beyond the capabilities Gravity Forms provides using custom CSS classes, etc.

In a future release we plan on adding the ability to edit the actual markup, but that will most likely be a 2.0 feature.

Yes this is possible, using CSS. You would need to know how to float elements using CSS in order to do this. If you create your form, and then show us where we can see your form I can look at the HTML and give you a quick code snippet you could use to accomplish this.

Fred,

You can try adding these declarations to your style sheet.

.gfield_checkbox {
	overflow:hidden;
}

.gfield_checkbox li {
	width:44%!important;
	float:left;
}

that should float the checkboxes into 2 columns like your example form.

If you don't want all the checkboxes formatted that way, you can specify the ID of the field/list so only those float.

#input_1_86.gfield_checkbox {
	overflow:hidden;
}

#input_1_86.gfield_checkbox li {
	width:44%!important;
	float:left;
}

where "input_1_86" is the ID of your field
