Hello @bakhshi
Yes, of course, it is simply CSS. The summary fields include pair of predefined class names assigned to the fields’ labels and values:
summary-field-title
and
summary-field-value
You can replace them with the class names you want through the settings of summary field.
So, you can enter the style definition below, into the “Customize Form Design” attribute in the “Form Settings” tab (https://cff.dwbooster.com/images/documentation/form-settings-tab.png) to display the summary as an unique row:
#fbuilder .summary-field-title,
#fbuilder .summary-field-value{float:left; clear:none;}
#fbuilder .summary-field-value{margin-right:40px;}
Editing the CSS rules you can give them the appearance you want to the summary.
Best regards.
