Accepted Solution Posted: 3 years agoChinmai_Sravanthi PEGA replied to allacHi, Thanks for posting your query to PSC:) Optimized code - Recommended option. Select optimized code to use flexbox-based layout in your form which helps you in achieving responsiveness. Legacy code - Select legacy code to use float-based layout in your form. This type of layout uses the inline block when setting several layouts side-by-side inline.
