From your RFP/Profile Dashboard, click on the greyView or Write tile (text depends on the status and phase of your RFP).
Once your RFP opens up, look for the Vendor Preview toggle at the top of your Sections on the left hand side of the page. The Vendor Preview option can be turned on at any time during the writing and approving process of your RFP or Profile. When you click on the toggle you have your choice of ON or OFF.
When the toggle button is turned to ON, the view will appear like this: You'll be able to see the Text Editor or Tables or Drop-Downs as you've specified.
