What determines lightbox row display vs colum display

For example, adding a type: time element triggers this layout in the lightbox (row display):

label field

In the CSS i’m seeing .gantt_wrap_section is added to rows.
Here is one of your examples: https://docs.dhtmlx.com/gantt/samples/05_lightbox/01_lightbox_customization.html

if I remove it, this happens


In the CSS, there are no .gantt_wrap_section elements.
Here is one of your examples, where it’s row display: https://docs.dhtmlx.com/gantt/samples/05_lightbox/03_validation.html

Is there a way to control this from the API?

Figured it out:

gantt.config.wide_form = true;
