In the Core PDF templates (and the majority of Universal templates), column layouts are supported when using Gravity Forms Drag and Drop column feature in the Form Editor.
In the Form Editor you to easily build advanced form layouts visually. Fields can be placed into columns and then resize to varying widths. Gravity PDF will automatically mimic your form column behaviour (when a template supports it).
Gravity Forms doesn't allow the following fields to be used in drag-and-drop columns and Gravity PDF will match this behaviour:
If you upgraded from Gravity PDF v5 or earlier, had previously run the Setup Custom Template tool, and didn't complete the v5 to v6 migration steps, the Core templates may be outdated and won't support Drag and Drop Columns. You can check if this affects you by viewing the Gravity Forms System Status page.
You can create up to four columns per row in the Form Editor. The default output is for each column is to be of equal width, but you can resize individual columns to suit your needs eg.
20% / 80% or
25% / 25% / 50%.
You don't need each column to equal 100% of the row width. You could have a single column take up 50% and then start a new row, or display two columns at 25% each.
Gravity Wiz / Gravity Perks Nested Forms Support
Gravity PDF supports columns when rendering Nested Forms fields in Core/Universal templates. Provided you've taken advantage of Drag and Drop Columns when building the Nested Form, this feature is enabled automatically in your PDF.
