Build Multi-Column Screens in Flow Builder (Pilot)
Multi-column layouts have hit Flow Builder! You can use the new Section component to arrange your flow screen components into multiple columns without touching a single line of code. Divide each flow screen into multiple sections, and easily modify the number of columns in each section to create effective, visually appealing layouts.
